Product Overview
The CGS Tool HV143-2502 has a 1/4” diameter, 4-flute, solid carbide corner radius end mill, built for high-performance machining in steels and alloys. It sits inside the Hi-Velocity (HV) series, so you get that kind of strength, speed, and precision you usually don’t see, not just for roughing but also for finishing work, at the same time.
Made from premium micro-grain carbide, the HV143-2502 comes with a variable helix and variable index geometry, plus an ALTiN coating, which helps with heat resistance and longer tool life when you’re running at high RPM. The free-cutting style helps the surface come out cleaner and keeps chips moving out of the way, while also reducing vibration and wear, so machinists can push feeds-and-speeds further without losing accuracy.
