Kennametal 2229653 Turning Insert CNMG431MS K313 Carbide

Product Description

The KENNAMETAL 2229653 is a CNMG431MS solid carbide turning insert in the K313 uncoated grade, designed for precision metal-cutting operations on CNC lathes and turning centers. Built to ANSI and ISO standards, this insert features an 80-degree diamond shape with a negative rake angle of 13 degrees, a 1/2-inch inscribed circle, and a 1/64-inch corner radius. The bright, uncoated carbide construction targets non-ferrous metals and superalloys including titanium, where uncoated substrates typically outperform coated alternatives. With four usable cutting edges and a honed edge style, this insert is intended for use by machinists and CNC operators in production turning environments.

This insert is suited for turning, facing, and boring operations on non-ferrous workpiece materials and superalloys and titanium. The MS chip breaker geometry controls chip flow during light-to-moderate cutting passes. The CNMG-style insert fits KENLOC-series toolholders that accept the standard clamp-and-pin holding method. Maximum depth of cut is 1.25 mm (0.0492 inches). The insert is sold individually per package, with a minimum order quantity of 5 units.

Key Features

• Solid carbide, uncoated (bright finish) K313 grade optimized for non-ferrous metals and superalloys
• 80-degree diamond insert shape with negative rake angle for stable, rigid cutting
• MS chip breaker geometry for controlled chip evacuation on light-to-moderate cuts
• Four cutting edges per insert for extended tool life across multiple indexing cycles
• Honed cutting edge style reduces micro-chipping on difficult materials
• Compatible with clamp-and-pin holding method for secure seating in KENLOC toolholders

Compatibility

Designed for use in KENLOC-series toolholders that accept CNMG-style inserts with a clamp-and-pin holding method. Industry standard number CNMG431MS. Fits toolholders conforming to ANSI and ISO insert seating standards for CNMG 431 geometry.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before indexing or replacing inserts. Seat the insert firmly against the pocket locating surfaces before engaging the clamp-and-pin mechanism to prevent micro-movement during cutting. Inspect the insert pocket for chips or wear before seating a new cutting edge.
