Kennametal 2229693 Turning Insert DNMG432MS K313 Carbide

Product Description

The KENNAMETAL 2229693 is a solid carbide, uncoated turning insert in the KENLOC series, designed for precision metal removal on CNC lathes and turning centers. It carries the ANSI designation DNMG432MS and the ISO designation DNMG150408. The insert features a 55-degree diamond (rhombic) shape with a negative rake angle of 13 degrees and a neutral hand orientation, making it suitable for a broad range of turning, facing, boring, back turning, and back boring operations. The MS chip breaker geometry is optimized for roughing and medium machining applications. Grade K313 delivers high to moderate wear resistance combined with toughness across stainless steel, cast iron, and non-ferrous workpiece materials.

This insert is intended for use in industrial turning operations on CNC and manual lathes where consistent chip control and tool life are priorities. Typical workpiece materials include non-ferrous metals, superalloys, titanium, stainless steel, cast iron, and aluminum. The four available cutting edges make it a cost-effective choice for high-volume production environments. It is held in the toolholder via clamp and pin method, which is standard for DNMG-style inserts in KENLOC-compatible toolholders.

Key Features

• 55-degree diamond insert shape with negative rake and negative side clearance for stable cutting geometry
• MS chip breaker supports roughing and medium machining with controlled chip flow
• K313 uncoated carbide grade rated for stainless steel, cast iron, aluminum, and non-ferrous materials at high wear resistance
• Four cutting edges per insert for extended service life per unit
• Compatible with clamp and pin insert holding methods used in KENLOC toolholders

Compatibility

Designed for use in KENLOC-series toolholders accepting DNMG432 insert style with clamp and pin holding. Suitable for turning, facing, boring, back turning, and back boring operations across workpiece material codes P, M, K, N, and S.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and de-energize the machine before indexing or replacing inserts. Secure the insert fully in the toolholder pocket using the clamp and pin system before resuming operation. Inspect the seating pocket and chip breaker seat for debris or wear prior to indexing to a new cutting edge.
