Kennametal 5697974 DNMG542RN KCP10B Turning Insert

Product Description

The KENNAMETAL 5697974 is a solid carbide turning insert designated DNMG542RN in ANSI coding and DNMG190608RN in ISO coding, finished in a multilayer CVD TiCN/Al2O3/TiOCN coating under the KCP10B manufacturer grade. The 55-degree diamond (rhombic) insert shape provides a sharp, defined cutting geometry suited to demanding metal removal. With a neutral hand orientation, a negative rake angle, and a chamfered and honed cutting edge style, this insert is engineered for high wear-resistance on steel and cast iron and moderate wear-resistance with toughness on aluminum and non-ferrous materials. Licensed machinists and CNC turning specialists working in production environments are the primary installers of this insert.

This insert fits into the KENLOC series toolholding system and is designed for multi-use turning operations including turning, facing, boring, back turning, and back boring. The RN chip breaker designation targets roughing and medium machining applications. Primary workpiece materials are steel and cast iron (ISO P), with secondary application to aluminum and non-ferrous materials (ISO N). The insert seats via clamp or pin holding methods in compatible KENLOC-style toolholders. It carries four usable cutting edges, maximizing value per insert in high-volume turning programs.

Key Features

• ANSI insert code DNMG542RN / ISO code DNMG190608RN with negative side clearance and 0-degree relief angle
• Multilayer CVD coating: TiCN base, Al2O3 intermediate, TiOCN outer layer for high wear-resistance on steel and cast iron
• RN chip breaker geometry rated for roughing and medium machining operations
• Four usable cutting edges for extended tool life across production runs
• Neutral insert hand — compatible with both right-hand and left-hand toolholder configurations where supported
• Compatible with clamp and pin insert holding methods in KENLOC series toolholders

Compatibility

Designed for use in KENLOC series turning toolholders that accept DNMG-style inserts with a 5/8-inch inscribed circle. Suitable for multi-use applications including turning, facing, boring, back turning, and back boring on steel, cast iron, aluminum, and non-ferrous workpiece materials.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Before seating the insert, ensure the toolholder pocket and clamping components are clean and free of chips or debris that could cause insert rocking. Torque the clamp or pin to the toolholder manufacturer's specification — do not over-tighten, as this can fracture carbide. Confirm insert seating and edge engagement before running the spindle.
