Carbide Tapered Ball End Mills McMasterCarr
These tools have a tapered profile and rounded cutting edge for making smooth contours on intricate, threedimensional shapes. They''re also known as taper degree end mills. Made of solid carbide, they''re harder, stronger, and more wear resistant than highspeed steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup
