drill millsMilling components with computer guiding machines is a great way to produce components quickly and efficiently. In order to cut the workpiece, these machines use specialized high speed cutting tools. Different end mills and drill bits are used to perform specific functions during the milling process. Most tasks require the use of several different tools during the machining process, which is what makes drill mills such great tools for machinists. These tools can perform a variety of different tasks, which makes them a great choice for any shop.
Drill mills are unique tools because they blend characteristics of both end mills and drill bits. This makes them extremely versatile tools for a wide variety of different uses. The most unique feature of these tools is the fact that they have a sharp point. This is not a typical feature for end mills, which are typically only designed for side milling operations. Drill mills have flutes that are designed for side milling as well as a pointed tip that can be used to drill down into a workpiece.
The ability to perform multiple actions with a single tool is a great way to cut down on cool changes and to speed up production. Drill mills can perform several different milling tasks. The pointed tip of the tool makes it perfect for chamfering or beveling edges. The body of the tool can also side mill, which is especially useful for when it comes to creating cutouts in a workpiece. The pointed tip can also be used when side milling, which makes it easy to cut V shaped notches in a workpiece. The point of these tools can also be used to deburr or engrave a workpiece.
What makes these tools so useful is the fact that they can be used for drilling operations as well. Obviously these tools can be used to drill holes that are the size of the tool itself. Drill bits are also notorious for "walking" off their mark due to their long length. This means that when using longer drill bits on a workpiece, it is often a good idea to spot drill the location of the hole first. As long as the point angle of a drill mill is equal to or greater than point angle of a larger twist bit, it can be used to spot drill the location of a hole.

A lot of people have moved into the machining industry lately. Especially with the appearance of more affordable CNC machines that allow anyone to craft custom parts right from their garage. However, many still render crudely finished products with sharp edges that make them quite dangerous depending on the intended use. That's where chamfer mills come into play.
It is common courtesy to chamfer any sharp edges off your parts or finished products to prevent accidents. Having a piece of furniture or piece that catches on clothes or causes some slashing damage can be grounds for serious problems.
Of course, you can create smooth surfaces by just filing your edges at a 45 degrees angle, or use a grinding disk. But when you´re machining, precision and accuracy are essential.
Chamfer mills provide both precision and speed. They not only take care of rough edges but also leave a much better finish. Additionally, they easily reach difficult angles without a problem and do a great job at smoothing out punched holes and prepping them up for threading.
Now, imagine we not only have to smooth out the surface, but we also need to modify the angle at which two surfaces meet. Carbide chamfer mills help you remove all those nasty 90 degrees edges and corners, creating a better-looking beveled slope while removing burrs along the piece.
This is also useful when preparing a piece for welding as chamfering provides a smooth surface to allow for a much stronger weld, and reduces the need for clearing excess material when finished.
A chamfer mill can also be used for finishing purposes. Carbide cutting tools have very sharp edges that easily remove material, leaving a perfectly polished surface that saves you time by eliminating the need of buffing out imperfections. I have found that machining and chamfering with carbide cutting tools make it easier to get parts that are ready for service right off the bat. Just make sure your bit engages the material correctly when machining tough alloys. A sharp edge can eat through your carbide and chip the tool easily if you´re not careful enough.
You can also use chamfer mills for engraving or creating channels along the surface without having to go through the finishing process. Carbide chamfer mills keep heat under control, allowing the drill to go through a lot of material without the risk of warp or chatter, leaving perfectly polished floors and walls.
So, even when your CNC or machining operations require minimum finishing, smoothing out edges and offering a polished surface is always a plus when delivering metal parts. We recommend having a few carbide chamfer mill bits in your arsenal. However, make sure they´re made here in the US from a manufacturer with great reviews. Our favorite is www-onlinecarbide.com as they offer incredible wear resistance and a great variety of tools for machining both soft and hard alloys. Their sales representatives are top of the line and provide advice on the right bits or angles for your machining projects.

Threads are an essential part of all sorts of components and connectors. From the pipes that feed water into our homes to the machines that make building those homes possible, threaded surfaces literally hold everything together. The process of cutting threads has taken many different forms over the years. Thanks to the popularity of CNC milling machines in the area of manufacturing, thread milling has become a popular way to add threaded surfaces to pipes and custom made components. If you want to thread mill efficiently it is important to know when to use single pitch thread mills.
Traditional thread making tools like taps and dies can have their drawbacks. They can take time and often require tool changes to produce threaded surfaces of different diameters and pitches. When chips fail to evacuate from these tools they can also cause some serious jams, potentially damaging the workpiece or the tool itself. Thread milling tools can tackle the same tasks in seconds with significantly less risk of the tool jamming or causing issues during the cut.
Some of the most common thread milling tools are known as full form tools. While these cutters are extremely fast and efficient, they are not always the best fit for a job. These thread cutting end mills have rows of sharp cutting teeth that are spaced to correspond to the desired thread pitch. When making a cut, the tool moves in a 360 degree angle while dropping the length of a thread pitch in order to form a uniform helical thread.
While this process allows threads to be cut in a second or less, it's still not always the best choice. Every full form tool can only cut threads with a uniform pitch, though they can be used to cut internal or external threads that are either left or right handed. These tools should only be used on very stable workpieces because they have a large cutting surface. If you have to deal with mixed thread sizes or unstable worpieces, then single pitch thread mills might be the best tools for the job.
Single pitch thread mills are designed with only a single cutting point instead of the full row of points found on a full form thread mill. This means that the tool has to trace along the entire threaded surface, which will take longer than using a full form tool. While the process might take a little longer, a single tool can create threads with a wide range of different pitch sizes, making them a great option. They can also be used to thread delicate surfaces like thin walled components and overhangs with ease.
If you are looking for some single pitch thread mills for your shop, then Online Carbide is the brand to check out. Their US made thread mills are second to none and are ground from high quality tool carbide stock. You can see their thread mills and all of their other cutting tools when you visit www.onlinecarbide.com.

When it comes to accuracy, milling machines are truly amazing tools. They are capable of performing extremely complex operations very quickly to shockingly tight margins of error. Sadly certain longer cutting tools like drill bits are not always the most accurate when using these machines. Luckily using spot drills to your machining process can significantly improve how accurate your longer twist bits can be.
So what is the issue with drill bits? Simply put, the issue is tool vibration. All high speed tools oscillate slightly due to the centrifugal forces they are encountering. When the tool is long relative to their width like a drill bit, this effect can be a little more pronounced. This can lead to the tool having enough of an oscillation that the point of the bit will be swinging around the center of the bit's rotation.
When a bit that is oscillating contacts a hard surface, it can deflect instead of penetrating as intended. This can even cause the drill bit to walk off its mark entirely. Obviously this is a big issue, especially when accuracy is crucial on your workpiece. One of the best ways to improve your accuracy is to create a surface that will provide your drill bit with an easier location to drill. This can be achieved through spotting.
Spotting is the process of creating small dimples on the surface of a workpiece to mark the location of future holes. The process is almost like countersinking for a hole that does not exist yet. The best tool for spotting is a spot drill. Unlike your average drill bit, a spot drill is not designed to drill deep holes. Instead, they are limited to a fluted point that is made to cut cone shaped dimples into your workpiece. These tools are short by design, which makes them extremely stable. Carbide drills are a great option because carbide's structure is more rigid and tolerant of heat than other tool materials like high speed steel.
The process of spotting is usually quick and easy, all you need to do is make sure the spot drill has a point angle that is larger than or equal to the point angle of your longer twist drill bit. As long as this is the case, you can drill all of your spots so that your longer twist bits will hit their marks perfectly. It's also important to make sure that you are using a proper spotting drill and not a center drill or similar looking tool that often may have a smaller point angle.
If you need high quality spot drills for your shop, then you can find some high performance solid carbide options when you visit www.onlinecarbide.com. All of Online Carbide's tools are manufactured in America using high quality carbide stock. If you have any questions about any of the tools that they offer, feel free to reach out to a member of their team by sending an email to sales@onlinecarbide.com.

If you are not already using TiAlN coated end mills, you might want to make the switch. End mills and other milling cutters have to tolerate extreme forces and temperatures, which can shorten their tool life. If you are not using coated tools, then you might not be getting the most out of your cutters.
End Mill Fatigue
All high speed tools have to deal with fatigue. The strain caused by friction at high speeds is immense and can even damage your tools. This is particularly true with end mills made from steel alloys due to the fact that their hardness is directly related to the temperature at which they are tempered. If the heat from friction rises above the tempering point, the structure of the metal can realign into a pattern that is not as hard, limiting the effectiveness of its edges.
One way to avoid this is to use tools made from carbide, which get their cutting power from grains of carbide ceramic embedded in the tool stock instead of from heat tempering. Despite being more resistant to heat and lasting longer than steel tools, carbide tools will still fatigue over time. One of the best ways to extend the life of any milling cutter is to coat it in a material like TiAlN.
Titanium Aluminum Nitride
Known by its chemical shorthand TiAlN, titanium aluminum nitride is a special metastable tool coating. TiAlN coated end mills are capable of deflecting heat away from the body of the cutter and into the chips. One of the biggest benefits of TiAlN is the fact that it has a low coefficient of friction, which helps to limit wear resistance and less heat is generated. When heated, TiAlN produces a layer of aluminum oxide that helps to provide extra insulation during high heat applications.
Physical Vapor Deposition
Now when you think of a tool coating, you might worry that the thickness of the coating material could interfere with the sharpness of the tool's edge. This would certainly be the case if we were talking about a coating that was crudely applied like paint, but tool coatings are deposited using physical vapor deposition. There are several techniques that are used but all involve placing the tools into a vacuum, vaporizing the coating material, and then having it resolidify on the tool surface. The major advantage of this is that a stable coating that is a fraction of a millimeter is achieved. Because the process takes place in a vacuum, the coating bonds directly to the body of the tool and offers incredible protection.
If you are interested in having tools that can run faster and last longer, then the TiAlN coated end mills available from Online Carbide are the perfect option. These tools are precision ground in the Us from high quality carbide and treated with titanium aluminum nitride TiAlN coating to offer a smooth surface finish that can withstand high temperatures. All of their tools are available at manufacturer direct prices when you visit their online store at www.onlinecarbide.com.

Milling machines are amazing pieces of machinery for several reasons. Using specialized cutting tools, a computer guided milling machine can perform extremely complex jobs in a fraction of the time that it would take using other machines. One of the downsides to operating at high speeds is the fact that it can often lead to extremely loud tool chatter. The best way to cut down on chatter without slowing down production is to switch to variable end mills.
Tool chatter is a noise caused by the vibrations of your cutting tools. The effects of chatter can vary dramatically depending on the materials being cut, the end mill being used, and the speed and feed rates being used. All tools vibrate at high speeds because even very solid feeling materials like metals are actually flexible. To imagine the issue at hand, picture what would happen if you spin a length of rope between your hands. The rope with flex and bow outward and the exact same thing happens with your cutting tools, albeit to a lesser degree.
The tool paths being used by your machine cannot perfectly account for this effect. This means that your tools are swinging into and impacting the workpiece constantly, occasionally putting a large amount of strain on both the tool and the edge of the workpiece. Because these tiny impacts are occurring a fraction of a second apart, the sound that they make combines into a high pitch screeching sound.
Operating at lower speeds can help to reduce tool chatter, but it will also cost you time. If you want to maintain a fast paced production without having to deal with the ear splitting noise, then using a variable end mill might be the perfect solution. The idea of these tools is that they are designed to be slightly asymmetrical. This leads to the impact forces between cuts being slightly different.
So what is the advantage of asymmetry in your end mills? It's easiest to explain by imagining the process of dribbling a basketball. When you dribble a ball, you apply the same force every time the ball reaches your hand, which leads to a stable rhythm. That is the same thing that happens to your tools. When the impact force is uniform and the timing is evening spaced, the tool builds an internal oscillation that amplifies the vibrations. Variable end mills apply uneven forces, which makes it harder for the tool to reach a consistent rhythm. By breaking up those regular internal forces, you can reduce chatter and harmonics.
If you are tired of dealing with tool chatter, then adding some variable end mills to your arsenal is the perfect way to keep the volume down without slowing down production. You can find high performance variable helix end mills when you visit www.onlinecarbide.com. All of Online Carbide's tools are manufactured in the US from high quality solid carbide stock and are available at manufacturer direct prices. Pay them a visit if you are looking to save big on the tools that your shop needs.

Spot drills and center drills are part of any drilling and machining operation. One of the most important aspects of machining parts is to drive holes with laser precision accuracy. You know that a hole that is off by a tenth of a millimeter can render a part useless, and there are no “undo” hotkeys in this business.
The problem is that twist drills or “jobbers” tend to “walk-off” when they first come in contact with a surface, especially when milling hard metal and alloys, no matter how tightly secured they are to the spindle. This happens because they are usually longer and more flexible than stub and spot drills.
Center Drills
Now, many CNC enthusiasts like using center drills for spotting since they are usually cheaper, and easier to find. However, the intended function of a center drill is to create a hole that helps secure a part in a lathe.
I can see why it might be the first pick for many when they understand the importance of spotting, as the pilot tip might suggest that it is its main purpose. However, if your operation requires a lot of spotting, the brittle center drill tip will not last too long.
There is one other problem: the countersink. When you're spotting, you want a hole angle that is equal to or greater than the twist drill angle. If the opening is too narrow, the recently drilled dimple will be a death trap for your bits, especially if they´re carbide-coated.
Now, it does not mean that center drills are not good for spotting. They do a good job as long as you only use the tip of the pilot, and don't abuse the tool. As we said before, the tip is very brittle and can only take you so far.
Spot Drills
True spot drills are the perfect tool for the job. They are chubby and rigid and generally provide the perfect anchorage for your jobber. The chunky shank helps to keep the tip right on target, providing maximum accuracy, and preventing it from walking off.
Some might say that spot drills are not necessary, or even detrimental if you´re using carbide drills. However, longer drill bits with carbide-coated tips are still too flexible and will deflect off or even start a hole at the wrong angle.
So, what's the solution?
Just remember that the tip angle of your twist drill must at least match that of your spot drill. That is the best way to protect your sharp carbide edges to come in contact with tapered angles that can damage your carbide tips. A matching point angle will help your tool find purchase quickly and engage the material right off the bat.
There seem to be very few trustworthy spotting drill bit suppliers. If you want excellent customer service and really durable tools, visit www.onlinecarbide.com. They manufacture all of their carbide bits and have plenty of spot drills to choose from.

Using CNC milling machines to make custom components has helped to revolutionize several industries. If you work with milling machines, then you know just how quickly milling cutters can wear out due to fatigue. These tools work hard and many operators try to save money by buying carbide end mill sets. Most of these sets will include several different sizes of specific cutting tools so no single tool has to do all of the work.
Advantages of Carbide End Mills
One of the best things about buying carbide end mill sets is the fact that carbide tools last longer than tools manufactured from steel alloys. While carbide may look metallic, the superior cutting power of these tools actually comes from the ceramic tungsten carbide powder within the tool's surface. This ceramic material is cemented in place with metal to create a material that has the impact resistance of metal and the rigidity and cutting power of ceramics.
Though this material is a composite, tools ground entirely from carbide are referred to as solid carbide to differentiate them from tools that are metallic with carbide inserts. An added bonus of using solid carbide tools is the fact that the ceramic content itself is virtually unaffected by high temperatures. This means that you can run carbide tools at higher speeds and feeds than tools made from high speed steel and other metallic alloys.
Carbide End Mill Sets
Many manufacturers offer sets of solid carbide tools. These sets will include multiple sizes that can be used for different milling applications. Typically buying carbide end mill sets is a good way to get a variety of options all at once so you can get a lot of different jobs done using the same types of tools. This is beneficial for the machinist because when you know how a tool performs, it's easy to find other applications for the same tool in different sizes.
There are a few downsides to buying full sets of carbide tools. The biggest concern is where your tools are coming from. A lot of end mill sets are manufactured overseas and may not be made of the highest quality materials. Poor manufacturing can lead to tools with a shorter tool life so it is always better to find US manufacturers with high standards when buying tools. The other issue with buying full sets of end mills is figuring out what to do when one dulls before the others. Sometimes it can be difficult to find a replacement for a single piece of the set. When that happens you need to find another supplier that offers high quality solid carbide end mills.
Luckily for machinists who find themselves in this predicament, there is Online Carbide. At www.onlinecarbide.com you will find a great selection of US made solid carbide end mills and drill bits at manufacturer direct prices. So if you need to replace a piece of your carbide end mill set, pay their online store a visit to find some amazing high performance milling tools.

When it comes to milling tools, most cutters are only designed for a singular purpose. That is one thing that makes drill mills shine. These versatile cutting tools are designed to perform a wide range of tasks, making them a must have for any machining shop. These specialized cutting tools are designed with the cutting flutes of an end mill and the pointed tip of a drill bit, giving them some of the strengths of both of these cutting tools.
Drilling
One of the most obvious advantages of using a drill mill is the fact that it can perform drilling operations. Most end mills excel at side milling, but have difficulty forming drilling tasks. You can easily use these tools to drill small holes, though they will rarely have the length needed to drill deep holes in your workpiece.
Spotting
The point on these cutters can also be used to spot drill locations for using longer twist bits. It is important to make sure that the point angle of your drill mill is equal to or greater than the tip angle of your longer drill bit in order to ensure that your bit will seat itself properly. This will help ensure that you produce clean and accurate holes.
Milling
Because of the flutes on these tools, they can also perform side milling tasks. The point can be used to side mill V shaped notches quickly and easily. If you have a sacrificial material underneath your workpiece, you can easily drill through it and begin the milling process.
Chamfering
The pointed tips on these tools also makes them well suited for chamfering and beveling. Many people confuse these two terms. Chamfering involves removing part of a corner in order to create a third intermediary plane between the original two sides. Beveling involves removing material in order to change the angle at which two sides meet. The pointed tip of a drill mill can perform both of these operations.
Finishing
Along with chamfering and beveling, you drill mills can be used to perform a few other finishing operations. You can use the point to trace along your workpieces edges to deburr them with the sharp point of the cutter. You can also use the points on these tools to perform simple engravings when you are finishing your piece.
If you need some of these useful cutters for your machine shop, then you need to visit www.onlinecarbide.com. Online Carbide manufacturers all of their tools from solid carbide tool stock. This means that you can expect a longer tool life and superior edge retention to similar tools made from steel alloys. Their drill mills are available in a range of sizes and with either a polished carbide finished or coated in TiAlN. All of their tools are available at manufacturer direct prices. If you have any questions about any of their tools, feel free to send an email to sales@onlinecarbide.com.

If you work with milling machines, then you know just how common tool changes are when operating these machines. This is because the tools used in milling operations are often designed to serve very specific purposes. Tools that can serve several functions are unique and extremely useful because they can help users cut down on their tool changes. Drill mills are one type of milling cutter that can perform a handful of different functions using the same tool.
As their name suggests, a drill mill is a tool that shares characteristics of both end mills and drill bits. The flutes are designed with sharpened edges like end mills, allowing them to perform side milling operations. The unique thing about these tools are their sharp points. These points, reminiscent of the tip of a drill bit, are responsible for the bulk of these tools’ versatility.
The ability to perform drilling operations is one of the most important aspects of using drill mills. The pointed tips on these tools make it possible to drill down into a workpiece. You can use these cutters to drill small holes that are the size of the tool itself. The tip can also be used for spot drilling, as long as the point angle is equal to or greater than the point angle of your longer twist bit.
The pointed tip on these tools can also be used for a number of finishing applications. This includes being used to chamfer or bevel edges. Just like a chamfer cutter, the tip on these tools is also great for deburring the edges on your workpiece. You can also use the tip to perform fine detail work such as custom engraving.
In addition to drilling, these tools are also designed to perform milling cuts. The point tip means they are perfect for cutting V shaped notches, though they can also be used to perform other milling tasks. The fact that they can drill through material and then being side milling makes these tools perfect for quick and easy removal of material, especially if there is sacrificial material beneath your workpiece. All of these different operations can make these tools invaluable for milling machine operators.
If you are looking to find some high quality drill mills for your shop, then you need to check out the solid carbide cutting tools available at Online Carbide. Unlike steel tools, carbide tools are made with a composite material of ceramic carbide powder and a bonding metal like cobalt. The ceramic content gives these tools incredible edge retention and heat resistance.

Buying a carbide end mill set is a great way to save money on high quality cutting tools, but there will always be a few pieces in the set that will get used over and over while others remain in their case. If you have noticed that your favorite end mills are starting to wear down, it might be time to find a replacement. Finding a replacement for one of your tools can be a tricky process and it’s important to keep a few things in mind.
When you bought your carbide end mill set, you were probably trying to find a wide range of tools in order to handle several machining tasks. The first tools that wear out from these kinds of sets tend to be the tools that have been most useful in your milling operations. That means that when replacing them, it's important to invest in high quality options. Investing in great tools now will ensure that your new cutter will have a longer tool life so that you can get more jobs done before having to worry about another replacement.
Solid carbide construction is one of the best options when it comes to end mills and drill bits. This is because carbide has several advantages when compared to tools made from steel alloys. These tools can hold their cutting edge remarkably well and they offer superior heat resistance. This is all the result of the fact that carbide tool stock is a combination of a metal binding agent along with ceramic tungsten carbide.
The ceramic carbide content of these tools is what gives them their incredible cutting power. Not only is carbide more rigid and dense than steel, but it does not suffer from the effects of heat tempering. This means that your tools can run faster and stay sharp for longer. Sadly not all carbide is created equal. If you want the best tools, it is important to make sure that you are ordering from a manufacturer that makes their tools from high quality micrograin carbide tool stock.
One of the best ways to find quality tools is to purchase them from a manufacturer that you can trust. It’s common practice to buy cheap carbide end mill sets from overseas to save money. Sadly these cheap tools tend to fail quickly and customer service can be difficult to reach, especially during your normal business hours.
If you are looking to find some quality replacement tools for your carbide end mill set, Online Carbide is a good place to find them. They are an American tool manufacturer specializing in drill bits and end mills. All of their tools are made using quality micro grain tungsten carbide stock and are made using the same precise computer guided grinding tools as industry leaders to ensure that they only produce sharp and accurate cutting tools.If you have any questions about any of the products that they offer, you can contact a member of the Online Carbide team by sending an email to sales@onlinecarbide.com.

Drill bits are essential manufacturing tools that are often subjected to a lot of use and abuse. Because these cutting tools regularly have to undergo exposure to high friction forces and the heat that results, bits can wear down quickly. If you are trying to find the right drill bits for your shop, it’s worth taking the time to make sure that you are ordering your tools from a reliable drill bit manufacturer. Working with reliable manufacturers will ensure that your shop will have tools that will get the job done and last longer than other options.
Location
One of the biggest factors when it comes to choosing a drill bit manufacturer is their location. Many machine operators try to save money by buying their tools overseas. Sadly the reduced price tag usually comes with a different kind of cost. Tools manufactured overseas are often of inconsistent quality and can quickly dull or fail unexpectedly. Dealing with American manufacturers helps to ensure that you are buying tools that are made with reliable materials and have undergone proper quality control testing.
Another distinct advantage of ordering tools from American manufacturing companies is the fact that US based businesses share similar hours to US based machining businesses. This means that if you do experience an issue with your tools, you can usually reach a customer service associate when you need them instead of having to leave a message or send an email that might sit unopened for days.
Material
Another huge factor to consider when choosing your tools is their material composition. Hardened steel tools tend to be an affordable option and high speed steel(HSS) drill bits and end mills have become increasingly popular due to their ability to keep their temper even under the temperatures that come with high speed machining. Despite the advantages of HSS alloys, even the finest tool steel is still no match for carbide tool stock.
Carbide tools are made using tungsten carbide tool stock. This material combines ceramic carbide material with cobalt metal as a binding agent. The cobalt metal provides strength while the ceramic material serves as a heat resistant material that helps to keep edges sharp and keeps your bits rigid. This means that carbide drill bits will be more accurate and they will last longer than steel twist bits.
If you are looking for high performance solid carbide drill bits for your shop, you need to check out the options available from Online Carbide. Online Carbide is an American drill bit manufacturer that creates high quality end mills and drill bits from micro-grain tungsten carbide tool stock. Their tools are machined using extremely accurate CNC grinding machines and sold at manufacturer direct prices. This means that your shop can get a great deal on the drill bits that they need. The Online Carbide catalog includes jobber drills, stub drills, spot drills, center drills and a wide variety of end mills. If you have any questions about any of their products, you can send their team an email at sales@onlinecarbide.com.

All cutting tools will suffer fatigue over time, including drill bits. When it comes to finding the right drill bits for milling machines, especially high speed milling machines, being able to resist corrosive forces is paramount. One way to make sure that your bits can handle any task your shop might need is to buy carbide drills. These tools offer several advantages over their steel counterparts that make them the clearly superior option for manufacturing cutting tools.
Carbide is a remarkable material when it comes to producing tools. While carbide might look metallic, this is only partially the case. The actual carbide in carbide tool stock is tungsten carbide, a ceramic material with some remarkable properties. This material is roughly twice as strong and twice as dense as steel. Sadly carbide cannot do much on its own, as ceramics are susceptible to shattering under strains. In order to produce tool stock, powdered carbide has to be mixed with cobalt metal which serves as a binding material.
The resulting sintered carbide material has many properties that make it ideal for producing tools. One of the biggest advantages of carbide drills is their ability to resist heat and retain the sharpness of their cutting edges. The ability that allows metal to retain a sharp edge is heavily influenced by how the metal is heat tempered. Tempering locks the arrangement of atoms in metal’s atomic structure, but high heat can cause metals to lose their temper and shift into less ideal patterns, softening the metal.
Because carbide’s strength comes from its ceramic content, the issue of the edges softening from becoming too hot. This means that solid carbide drill bits can operate at much higher speeds and be used on herder materials like steel and cast iron without the operator having to worry about damaging their tools or their workpiece.
In addition to being tougher than your average metal tools, carbide bits are also more rigid. When a drill bit spins, it also flexes and oscillates. This is similar to how a piece of string might bow widely if spun between the palms of your hands. The effect is far less pronounced with a drill bit and can barely be observed with the naked eye, but this effect can cause drill bits to miss their mark and deflect off of your workpiece. When you buy carbide drills, you are investing in tools with less oscillation that are capable of drilling holes with significantly more accuracy.

When it comes to machining components that need to have solid connections, you need to make sure that you have accurate thread mills. The process of thread milling requires making highly accurate cuts so that your components will be able to fit together as intended. If you want to ensure accurate results, you need to complete your work using Solid Carbide Thread Mills. Here at Online Carbide, we make all of our milling cutters to our exact standards using top of the line solid carbide stock. These tools are designed to perform the cuts you need within precise tolerances and can cut a diverse number of thread designs to meet any shop’s needs.
Thread milling is a tricky but necessary part of machining. This process used to only be completed using specialized tools call taps and dies. These tools can cut accurate threads, but often require the operator to cut the threads by hand, which can be cumbersome and time-consuming. Using thread mills is a great way to simplify this process.
Here at Online Carbide, we offer two styles of thread mills. The first style is our single pitch thread mills. These end mills are designed with a small shank and a round cutting head with a rough rhombus-shaped cross-section. These tools are suited to a wide range of thread cutting needs including medium to large internal threads of larger external threads, particularly on asymmetric components. They are also ideal for components that are not extremely stable, due to their small cutting surface. This makes them perfect for thin-walled parts or dealing with large overhangs. You can also use these single pitch mills to cut the same insert sizes, but with different thread pitches.
Our next option is our full form thread mills. These mills have a sturdy tapered cutting surface with threads and rows of triangular “teeth” between the threads. Unlike single pitch mills, these end mills are designed to complete your part’s threads using one 360-degree cut. As long as the thread pitch is identical, these end mills can cut multiple thread sizes with the same tool. They will also chamfer while they cut your threads.
We offer all of our solid carbide thread mills in a range of sizes. Our Single pitch thread mills are sold based on thread size and threads per inch. Our full form thread mills are divided based on UN, metric, NPT, and NPTF thread options. All of our thread mills are coated with a TiAlN layer to protect from heat and extend their tool life.
So if you work in a shop that regularly has to cut threads, it’s time to look into the high-quality solid carbide thread mills from Online Carbide. All of our cutting tools are made using the highest quality carbide stock and ground to exact tolerances using our robot FEC 5 Axis CNC grinders. If you have any questions about our inventory, feel free to reach out to a member of our team via phone at 630-238-1424 or email at sales@OnlineCarbide.com.

While machining harder materials like steel can but some serious wear on your end mills, people often underestimate how difficult machining soft aluminum can be. If you go into an aluminum milling project without the correct cutting tools, you may damage both your cutter and your workpiece. We have looked at the challenges aluminum can pose and have created the Best End Mills For Aluminum in order to help our customers machine with ease.
Here at Online Carbide, we are dedicated to providing our customers with top of the line carbide cutting tools. We use the same high-quality solid carbide stock as other industry leaders, we never offer carbide coated or tipped tools. We use robot fed 5 axis CNC grinders to produce our cutting tools to precise tolerances. This helps ensure that every tool we sell will perform as expected. We also only sell directly to our customers. These manufacturer direct prices will help you avoid the mark up that most stores put on cutting tools after purchasing them from the manufacturer.
There are several aspects of aluminum that can make it a tricky material to machine. The biggest concern when working with aluminum stems from the small chips that are produced. The chips from aluminum are so small they are basically a powder. This means that if the chips are difficult to evacuate from the cutting area. If too much aluminum powder builds up about your cutter, it can easily start to cake up back into a solid mass. If this occurs it can severely damage your end mill.
In order to help with chip evacuation, the best end mills for aluminum will have a lower flute count compared to tools for steel. This gives the chips more room to evacuate. We make our end mills using a 37-degree helix angle which is also intended to increase the evacuation rate. These features make it much easier to work on aluminum without worrying about unexpected tool failure.
The final feature that makes our end mills the best end mills for aluminum is the coating. We coat all of our tools intended for aluminum with a layer of zirconium nitride. This is a golden-colored ceramic coating that has extremely low surface friction, making it harder for chips to stick. It also helps to greatly increase the life of tools by protecting the tool’s cutting surfaces.
If you work in a shop that regularly deals with machining aluminum, you know how important it is to attack every job with the right tools. If you’re ready to upgrade to the best end mills for aluminum, it's time to visit us at Online Carbide. If you have any questions about our end mills for aluminum or any of our other products, feel free to contact a member of our team at sales@onlinecabide.com or call us weekdays between 8-5 CST at 630-238-1424.

Chamfer cutters are one of the most frequently used end mills in a machinist’s toolbox. This is because they are perfect for finishing projects and taking care of small details. Chamfering is the process of adding a flat surface as a transitional edge between two faces on an object. The most typical form of chamfering is at a 45° on a 90° corner. Though Chamfer Mills are specifically designed for adding a chamfer to your edges, they can serve many additional functions that you might not have considered.
One of the chamfer mills obvious functions is beveling an edge. Many people actually confuse a chamfer and a bevel. While a chamfer affects only the edge where your sides meet, a bevel affects an entire edge. How effective your chamfer cutter will be when beveling an edge depends on your workpiece. If the piece is thin enough, you can easily bevel the edge by orienting the tip of your chamfer mill along the bottom edge of your piece. If you are dealing with thicker material, you can achieve a bevel with multiple passes of your chamfering mill.
Deburring is another job perfectly suited to a chamfer mill. When your milling is complete, you are bound to have some stray burs left on your piece. By tracing the edges you just cut with your chamfering mill, you can avoid the time-consuming process of manually deburring your piece. You can also deburr using only a small portion of the cutting head, meaning the job can be done quickly with minimal wear to the cutter.
Another excellent way to get some more utility out of your chamfer cutters is to use them for spotting and countersinking. Long drill bits tend to have a bit of flexibility to them. This can easily cause them to wander instead of placing your hole exactly on target. By spot drilling a dimple to receive the bit, you can avoid these deflections that can easily ruin your workpiece. Once your hole is drilling, your chamfer mill can also be used to widen the top of your hole to add a countersink. Instead of using three separate tools to spot and countersink, you can get it done using only your trusty chamfering mill.
With all of these functions, it’s clear that having quality chamfer cutters on hand is crucial to getting your work done efficiently. At Online Carbide, we manufacture our solid carbide chamfer mills here in the USA. When you buy chamfer mills from us, you get the mills made to the same high standards as the major brands, but without dealing with markup from middle men. You can purchase our chamfering mills in ¼”, ?”, and ½” diameters with either 60° or 90° tip angles.
We are dedicated to making the best carbide cutting tools on the market. No matter what you need to get your next job done, you can trust Online Carbide to provide the quality milling tools your shop needs at an amazing price.

Whether you’re working with wood or metal cutting machines, having a wide assortment of end mills will make finding the right tool for the job easier.

Even with the best possible settings, you will also notice a huge difference in tool fatigue based on where you buy your end mills. While cheap end mills can be found, typically from overseas manufacturers, these end mills are often constructed from low carbide grades. When these cheap end mills go up against a material as hard as stainless steel, the high temperatures will wear them down quickly.
