Product Overview
The CGS Tool HV140-6250 has a 5/8” diameter, 4 flute solid carbide square end mill, it is engineered for high performance machining in steels and alloys. It comes from the Hi-Velocity (HV) Series, so it aims at unmatched strength, speed, and precision, for both roughing and finishing, even if you’re doing it all day.
Made from premium micro grain carbide, the HV140-6250 has a variable helix and variable index geometry and it also includes an ALTiN coating, which helps a lot with heat resistance and overall tool life when the RPMs are up. The free-cutting design helps with better surface finish and chip evacuation , and it also reduces vibration plus wear, so machinists can push feeds and speeds further without giving up accuracy.
