Kennametal 5697962 Turning Insert DNMG331MN KCP10B Carbide

Product Description

The KENNAMETAL 5697962 is a DNMG331MN turning insert in grade KCP10B, designed for indexable toolholders used in CNC turning, facing, boring, back turning, and back boring operations. The insert features a multilayer CVD coating stack of TiCN, Al2O3, and TiOCN over a solid carbide substrate, providing high wear resistance on steel and moderate wear resistance with toughness on aluminum and non-ferrous materials. The 55-degree diamond (rhombic) shape with negative rake and neutral hand makes it a versatile choice for general and roughing passes. Four usable cutting edges per insert extend tool economy. A chamfered and honed cutting edge geometry improves edge stability under interrupted and continuous cuts.

This insert is suited for turning steel and cast iron in medium to roughing chip-load applications, as well as aluminum and non-ferrous workpieces where a balance of wear resistance and toughness is required. The MN chip breaker geometry handles both roughing and medium machining scenarios, keeping chip control manageable across a range of feed rates and depths. It fits into KENLOC-series toolholders that accept DNMG-style inserts secured by clamp or pin. Typical applications include shaft turning, facing operations on lathes, and boring on machining centers where a D-style insert seat is present. The part is sold individually but must be ordered in multiples of five.

Key Features

• Multilayer CVD coating: TiCN plus Al2O3 plus TiOCN for high wear resistance on steel (P) and toughness on non-ferrous (N) materials
• 55-degree diamond insert shape with negative rake and 0-degree relief angle for strong edge support
• MN chip breaker supports both roughing and medium machining operations
• Four cutting edges per insert for extended tool life and lower cost per edge
• Chamfered and honed cutting edge style balances sharpness with edge stability
• Compatible with clamp and pin insert holding methods; fits KENLOC-series toolholders

Compatibility

Designed for KENLOC-series indexable turning toolholders that accept DNMG-style inserts with a negative, 55-degree diamond seat. Compatible with both clamp-style and pin-style insert retention systems. ANSI insert code DNMG331 and ISO insert code DNMG110404 can be used to cross-reference compatible toolholder seats.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or tooling technician with the machine in a full stop and locked-out state per applicable machine safety procedures. Use the correct torque driver or wrench for the clamp screw to avoid cracking the carbide or stripping the seat. Inspect the toolholder pocket and locating pin for wear or debris before seating a new insert, as a contaminated pocket will affect runout and edge life. Dispose of spent carbide inserts according to local regulations for tungsten carbide waste.
