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.
