HVM143-040 | 4mm 4-Flute Corner Radius End Mill | Hi-Velocity Series
The HVM143-040 from CGS Tool is a 4mm solid carbide end mill, 4-flute, corner radius profile. Built for steel, stainless, and hardened alloy work — roughing and finishing both.
Micro-grain carbide stock is used throughout. The flutes carry a variable helix and variable index grind, which breaks up harmonic vibration and keeps the cut stable at high RPM. ALTiN coating goes on top of that — it handles oxidation and thermal buildup well, so the edge holds longer on harder materials.
At 14mm LOC and 50mm OAL, the tool covers slotting, profiling, and finishing without a swap. Chip flow stays clean through the geometry.
