Kennametal 7064045 WNMG431 Carbide Turning Insert

Product Description

The KENNAMETAL 7064045 is a WNMG431 (ISO: WNMG080404) indexable carbide turning insert designed for external and internal turning operations on CNC lathes and turning centers. It carries grade KCP25C with an Al2O3 coating, a trigon 80-degree insert shape, and a corner radius of 0.40 mm (1/64 inch). The FV chip breaker geometry is optimized for finishing cuts. With 6 cutting edges per insert and a neutral hand orientation, it delivers consistent performance across multiple index positions before replacement. Machining professionals and CNC operators handling steel and non-ferrous alloys will find this insert suited to moderate wear-resistance and toughness demands in precision finishing work.

This insert is intended for finishing operations on steel (P-class) and aluminum and non-ferrous materials (N-class) where moderate wear-resistance and toughness are required. It fits standard WNMG-style toolholders with a negative side clearance (N) and tolerance code M. Typical applications include light to moderate depth-of-cut passes on turned components in job shop, production machining, and aerospace or general manufacturing environments where surface finish quality is a priority.

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. Use the appropriate torx or hex key to torque the clamping screw according to the toolholder manufacturer specification. Handle carbide inserts with care to avoid chipping cutting edges during installation.
