  • 1mm End Mills McMasterCarr

    For longer tool life and a better finish in general purpose milling applications, these solid carbide end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have a ball end for milling rounded ...
