Product Overview
The CGS Tool HV243-4375 has a 7/16” diameter 4 flute solid carbide corner radius end mill, made for really high performance cutting in steels and alloys. It’s built as part of the Hi-Velocity HV Series so you get this kind of strength, faster machining, and sharp precision for roughing as well as final finishing tasks.
Made from premium micro grain carbide, the HV243-4375 has a variable helix plus a variable index geometry, and it runs with an ALTiN coating. That combo gives standout heat tolerance and better tool life when you’re spinning at high RPM. The free cutting setup helps with smoother surface results and keeps chips moving out of the cut, so you can reduce chatter vibration and overall wear ,which means machinists can push feeds and speeds farther along without losing accuracy.
