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.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

The ball end mill should be used for roughing operations and most finishing operations. Its large radius dissipates the force and heat that is generated in cutting hard material at high speeds and feeds. The ball end mill allows the user to cut closer to the net threedimensional shape and allows for higher speeds and feeds.
