For longer tool life and a better finish in general purpose milling applications, these solid carbide end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface.
End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.
Uncoated Carbide—Use uncoated end mills for general purpose milling and short production runs.
Titanium Nitride (TiN)-Coated Carbide—Titanium nitride (TiN)-coated end mills create less friction than uncoated end mills, which means they last longer when run at similar speeds. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills.
Titanium Carbon Nitride (TiCN)-Coated Carbide—Titanium carbon nitride (TiCN)-coated end mills have a hard, smooth finish that resists chipping and wear and prevents material from accumulating on the cutting edge. They’re especially good for use in aluminum. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills.
Titanium Aluminum Nitride (TiAlN)-Coated Carbide—Titanium aluminum nitride (TiAlN)-coated end mills dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills.

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have a square end for milling square-bottomed slots, pockets, and edges.
End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.
Aluminum Titanium Nitride (AlTiN)-Coated Carbide—A titanium aluminum nitride (TiAlN) or aluminum titanium nitride (AlTiN) coating allows them to dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication.

Increase your productivity with these end mills that make a shallow cut and produce thin chips that are easily cleared. Often used for slotting and pocketing cuts in mold and die making, they have a 90° profile and rounded corners, which reduce flute breakage and chipping. Also known as torus end mills. All are noncenter cutting for operations where the peripheral teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.

Carbide Tapered Ball End Mills
 |
Tapered Cut Style |
 |
These tools have a tapered profile and rounded cutting edge for making smooth contours on intricate, three-dimensional shapes. They're also known as taper degree end mills. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. All are center cutting, allowing plunge cuts into a surface.
Uncoated Carbide—Use uncoated end mills for general purpose milling and short production runs. They stay sharper than coated end mills when used on soft materials like aluminum, leaving a better finish.
Aluminum Titanium Nitride (AlTiN)-Coated Carbide—Aluminum titanium nitride (AlTiN)-coated end mills are better for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills. They dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication.

Carbide Square End Mills for Aluminum, Brass, and Bronze
 |
2 Flutes |
 |
3 Flutes |
Either an aluminum non-ferrous (ANF) coating or a titanium carbon nitride (TiCN) coating prevents soft material, such as aluminum, brass, and bronze, from accumulating on the cutting edge and creating an uneven finish. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have a square end for milling square slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.
2 Flutes—End mills with two flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts.
3 Flutes—End mills with three flutes provide a finer finish and operate with less vibration when run at high speeds.

Fast-Cut Carbide Rounded-Edge Square End Mills
|
Rounded-Edge-Square Cut Style |
 |
5 Flutes |
Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. Often used for slotting and pocketing cuts in mold and die making, these end mills have a 90° profile and rounded corners, which reduce flute breakage and chipping. Also known as corner radius end mills.
Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking.
A titanium aluminum nitride (TiAlN) or aluminum titanium nitride (AlTiN) coating allows them to dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication. This makes these good for aggressive machining while roughing or making interrupted cuts.
End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.

Finishing Carbide Square End Mills
 |
Intersecting flutes create a fine finish, making these end mills good for operations requiring light stock removal, such as deburring, profiling, and finishing. Made of solid carbide, they’re harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills for the longest life and best finish on hard material. Since they have a fine pitch, they last longer than coarse-pitch end mills and produce smaller chips for better performance on harder metal, such as hardened steel and tool steel. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. All are center cutting, allowing plunge cuts into a surface.

Replaceable Carbide-Insert Chamfer End Mills
|
Chamfer Cut Style |
 |
Individual Carbide Insert Case |
 |
Cut down on waste and cost during high-volume jobs. These end mills consist of a holder and a carbide insert, so you can swap in a fresh cutting edge without replacing the whole tool. The inserts are locked in place with a screw for a hold that’s strong enough to handle the high speeds of a CNC machine. They’re held at an angle, so you can create chamfers, bevels, and other angled cuts. You can also use them like a face mill for flat surface cutting.
Inserts have a positive rake angle, which means the cutting edge is angled to reduce vibration and prevent thin workpieces from bending. For a longer life, each insert has two cutting edges—rotate the insert when the first side wears down. They have chip breakers to stop long chips from forming, so they won’t block the flow of coolant or damage your tool. Inserts sold individually come in a clear plastic case to prevent damage during shipping. Inserts sold in packs come factory sealed from the manufacturer, which makes them easy to trace.
