Kennametal 4082972 CNMG432MS KCS10 Turning Insert

Product Description

The KENNAMETAL 4082972 is a CNMG432MS KCS10 solid carbide turning insert with a physical vapor deposition (PVD) AlTiN coating. It features an 80-degree diamond (rhombic) shape, a neutral hand orientation, and a 0.0313-inch corner radius. The insert carries a negative rake angle of 13 degrees and a negative side clearance, making it suited for high-load turning operations. With four usable cutting edges and an MS chip breaker geometry, it is designed for roughing to medium machining passes. Licensed machinists and CNC turning specialists install this insert into KENLOC-style toolholders across production and job-shop environments.

This insert is intended for turning, facing, and boring operations on stainless steel, superalloys, titanium, steel, cast iron, and aluminum. The KCS10 grade is characterized by high wear resistance to moderate wear resistance and toughness across P, M, K, N, S, and H workpiece material codes. Its AlTiN PVD coating supports performance in interrupted cuts and heat-intensive applications typical of stainless steel and titanium work. The MS chip breaker geometry manages chip control during both roughing and medium machining cuts.

Key Features

• 80-degree diamond (C-shape) rhombic insert with negative rake and negative side clearance
• MS chip breaker optimized for roughing and medium machining chip control
• Four cutting edges per insert for extended tool life and lower cost per edge
• Compatible with clamp and pin insert-holding methods
• Meets ANSI and ISO standards; ANSI code CNMG432, ISO code CNMG120408

Compatibility

Designed for use in KENLOC-series toolholders accepting CNMG432 inserts secured by clamp or pin holding methods. Suitable for turning, facing, and boring applications across P, M, K, N, S, and H workpiece material categories.

Installation Notes

This insert is installed and indexed by qualified machinists or CNC turning technicians. Always power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque driver or clamp screw to secure the insert without overtightening, and inspect the insert seat and shim for damage before seating a new edge. Follow the toolholder manufacturer's clamping procedure to ensure proper insert location and rigidity.
