When one end wears out, turn the tool around for a sharp edge.
With a wearresistant coating and high helix angle, these end mills provide excellent shearing and chip removal in stainless steel and titanium. 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.
When one end wears out, switch to the opposite end for two times the life of a standard carbide end mill. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than highspeed steel and cobalt steel for the longest life and best finish on hard material. Use them to round sharp corners on the edge of your workpiece.
