The VNMG is a 35° rhombic negative rake cemented carbide turning insert equipped with BF finishing chipbreaker. With sharp optimized cutting edge and precision chip control geometry, it targets finishing turning of steel and alloy steel.

The VNMG-BM insert is the primary recommended chipbreaker for semi-finishing Group M materials. Edge honing suppresses built-up edge. Its 35° rhombic geometry minimizes interference and delivers superior profile-following capability for complex stainless steel contour turning.

Thanks to its sharp corner geometry and the stable chip‑breaking performance of GF chipbreaker, the VNMG‑GF insert is suitable for finishing turning of carbon steel alloy steel, stainless steel.It performs well in profile and internal continuous finishing operations on lathes.
