    These end mills have a long shank and a cutting edge that curves around the top of the ball end allowing them to reach into pockets to create undercuts. 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
