Product Overview
The CGS Tool HV140-3751 has a 3/8” diameter, 4-flute, solid carbide square end mill , made for high-performance machining in steels and alloys. It’s built under the Hi-Velocity (HV) Series, so you get that really strong mix of speed, precision, and sturdiness for roughing AND finishing jobs , not just one side of the work.
Made with premium micro-grain carbide, the HV140-3751 has a variable helix and variable index geometry, then gets an ALTiN coating for serious heat resistance plus longer tool life, especially when you’re running high RPM. The free-cutting style helps surface finishing and chip evacuation too, while also keeping vibration and wear lower, which means machinists can push feeds and speeds farther without losing accuracy.
