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.

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.

An aluminum-chromium-nitride (AlCrN) coating provides excellent resistance to wear, high temperatures, and oxidation—even at high speeds. Great for difficult-to-machine materials like stainless steel, titanium, and tool steel.
