Kennametal 3760969 TNMG332MP KCM25 Turning Insert

Product Description

The KENNAMETAL 3760969 is a TNMG332MP-style solid carbide turning insert in the KCM25 grade, designed for high-performance metal cutting in CNC and manual turning operations. Coated via MTCVD with a multilayer TiN/TiCN/Al2O3 system, it delivers wear resistance and thermal stability across a broad range of workpiece materials. The insert features a 60-degree triangle shape with a negative rake angle of 6 degrees, a chamfered and honed cutting edge, and 6 usable cutting edges per insert. With a 3/8-inch inscribed circle and a 1/32-inch corner radius, this insert fits standard KENLOC-series toolholders and suits turning, facing, and boring applications.

This insert is rated for primary use on steel, stainless steel, superalloys, and titanium, covering ISO material codes P, M, and S. The MP chip breaker geometry is suited for medium-depth passes, with a maximum depth of cut of 0.05 inches (1.25 mm). It is a neutral-hand insert, making it appropriate for a wide range of tool setups in production turning environments. The KENLOC series designation indicates compatibility with Kennametal-style clamp-and-pin holding systems. This insert is sold individually but requires a minimum order of 5 pieces.

Compatibility

Designed for use in KENLOC-series clamp-and-pin toolholders accepting TNMG332 inserts. Suitable for turning, facing, and boring of steel, stainless steel, superalloys, and titanium. Conforms to ANSI and ISO standards for TNMG-style inserts.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or clamp screw driver specified for the toolholder - do not overtighten the clamp, as this can fracture the carbide substrate. Inspect the insert pocket and clamp for debris or wear before seating a new insert.
