Miniature Carbide Rounded-Edge Square End Mills
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.
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.

Carbide Dovetail End Mills for O-Rings
Create dovetail grooves that allow O-rings to flex without falling out of place. Made of solid carbide, they 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.
