Product Overview
The CGS Tool HV140-3756 has a 3/8” diameter, 4-flute solid carbide square end mill, built for high-performance machining when you’re dealing with steels and alloys. It’s made to fit within the Hi-Velocity (HV) Series, so it brings that mix of strength, momentum, and precision for roughing and finishing jobs, depending on what you’re running that day.
Made from top-tier micro-grain carbide, the HV140-3756 has a variable helix and a variable index geometry. It's finished with an ALTiN coating that helps it withstand heat better and last longer at higher RPMs. The free-cutting style improves surface finishes and facilitates chip evacuation, while also reducing vibration and wear, allowing machinists to push feeds and speeds even further without sacrificing accuracy or control.
