Product Overview
The CGS Tool HV143-2500 has a 1/4” diameter, 4-flute solid carbide corner radius end mill, made for high-performance machining when you’re working in steels and other alloys. It sits in the Hi-Velocity (HV) series, so it can give you stronger, faster, sharper results for both roughing and finishing jobs, like you actually care about the final dimension and the surface at the same time.
Built from top-notch micro-grain carbide, the HV143-2500 features a variable helix and variable index geometry with an ALTiN coating. That combination improves heat resistance and helps the tool last longer when you’re running at higher RPMs. Also, the free-cutting style improves surface appearance and chip removal, while reducing vibration and wear, so machinists can push feeds and speeds more aggressively without sacrificing accuracy.
