Product Overview
The CGS Tool HV143-1877 has a 3/16” diameter, 4-flute, solid carbide corner radius end mill made to do high-performance work in steels and alloys. It’s built around the Hi-Velocity (HV) Series so it can give that kind of strength, pace, and accuracy you want, whether it’s roughing or finishing, not just one thing.
Made from top-grade micro-grain carbide, the HV143-1877 has a variable helix and variable index layout with an ALTiN coating, so heat stays under control, and the tool lasts longer when you’re running high RPM. The free-cutting style helps with surface smoothness and chip evacuation, while also keeping vibration and wear lower, which means machinists can run higher feeds and speeds and still keep accuracy, mostly.
