Kennametal 2229697 Turning Insert VNMG331MS KC5025

Product Description

The KENNAMETAL 2229697 is a solid carbide turning insert with a VNMG331MS geometry and KC5025 grade, coated with TiAlN via a PVD process. It features a 35-degree diamond (rhombic) shape, a neutral hand orientation, and a honed cutting edge style. The inscribed circle measures 0.375 inches and the corner radius is 0.0156 inches (1/64 inches). With 4 cutting edges and a negative rake and side clearance configuration, this insert is suited for moderate wear-resistance and toughness applications across steel, stainless steel, cast iron, and aluminum workpiece materials. It is installed by machinists and CNC operators in production turning environments.

This insert is designed for use in external and internal turning operations including facing, boring, back turning, and back boring. The MS chip breaker geometry supports roughing and medium machining operations. Primary workpiece materials include stainless steel and superalloys and titanium, with applicability across P, M, K, N, and S material codes. It is held by clamp or pin mounting in KENLOC-series toolholders. Typical applications include general-purpose lathe work and CNC turning centers in both light industrial and production environments.

Compatibility

Designed for use in KENLOC-series toolholders accepting VNMG-style inserts held by clamp or pin. Conforms to ANSI insert code VNMG331 and ISO insert code VNMG160404. Compatible with multi-use applications including turning, facing, boring, back turning, and back boring.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully in the pocket and verify clamp or pin engagement before resuming cuts. Do not exceed the maximum depth of cut of 1.25 mm (0.0492 inches) per pass for optimal edge life.
