With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. They have a square end for milling square 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.

Use uncoated end mills for general purpose milling and short production runs. Use titanium-carbonitride (TiCN) coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They 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.

Center-cutting end mills allow plunge cuts into a surface.

With a mill diameter less than 1/8", these end mills are great for precise, detailed work such as in electronics, mold making, and medical-device manufacturing. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface.

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.

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.

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.

These end mills have an extended neck with a reduced diameter that prevents them from rubbing against your workpiece when deep milling. Also known as runner cutters, they cut channels with precise angles and dimensions, reducing the need for additional finishing. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface.

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.

Use uncoated end mills for general purpose milling and short production runs. They will stay sharper than coated end mills and leave a better finish on soft materials like aluminum. Use aluminum-titanium-nitride (AlTiN) coated end mills 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.

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.

Flutes have a low helix angle to provide the cutting forces required for difficult-to-machine material, such as hardened steel and iron. 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 ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface.

An aluminum-titanium-nitride (AlTiN) or aluminum-chromium-nitride (AlCrN) 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.

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. Also known as taper degree end mills, they're often used to machine angled slots in dies and molds.

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.

This makes these good for aggressive machining while roughing or making interrupted cuts.

Noncenter-cutting end mills are 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.

Replicate the shape of complex parts with these end mills. Also known as torus end mills, they have a rounded edge for precision contouring. These end mills are also used for slotting and pocketing cuts in mold and die making. Their 90° profile and rounded corners reduce flute breakage and chipping. All are center cutting, allowing plunge cuts into a surface.

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-silicon-nitride (TiAlSiN) coating makes them extremely resistant to wear and diffusion because they have especially high hardness, even at high temperatures.

With a mill diameter of 3 mm or less, these end mills are great for precise, detailed work such as in electronics, mold making, and medical-device manufacturing. 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. All are center cutting, allowing plunge cuts into a surface.

End mills with two flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts.

End mills with four flutes provide a finer finish and operate with less vibration when run at high speeds. They have variable spacing between the flutes which reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials.
