Kennametal 3749293 WNMG332RP KCP10 Turning Insert

Product Description

The KENNAMETAL 3749293 is a WNMG332RP KCP10 grade solid carbide turning insert designed for high-productivity metal removal on steel and cast iron workpieces. The insert features a multilayer MTCVD coating combining TiCN and Al2O3, delivering high wear resistance on steel (P) and moderate wear resistance with toughness on aluminum and non-ferrous materials (N). The 80-degree trigon (W) shape provides a strong cutting geometry with a negative rake angle of 5 degrees and a chamfered, honed cutting edge style. Six usable cutting edges maximize tool economy. With an inscribed circle of 0.375 inches and a corner radius of 0.03125 inches, this insert is suited to roughing and medium machining operations.

The 3749293 is applied in turning, facing, and boring operations across general metalworking environments. Its KENLOC series designation indicates compatibility with Kennametal KENLOC-style insert toolholders. Primary workpiece materials are steel and cast iron, with secondary suitability for aluminum and non-ferrous alloys. The RP chip breaker geometry is optimized for roughing and medium machining passes, helping manage chip evacuation during deeper cuts. The insert is held by clamp or pin methods and carries both ANSI (WNMG332) and ISO (WNMG060408) designations, making it straightforward to cross-reference against toolholder requirements in either standard.

Key Features

• KCP10 grade with multilayer MTCVD TiCN and Al2O3 coating for high wear resistance on steel
• 80-degree trigon (W) shape with negative side clearance for strong edge support
• RP chip breaker suited to roughing and medium machining operations
• Six cutting edges per insert for maximum utilization
• Neutral hand orientation for flexible toolholder pairing
• Clamp and pin insert holding compatibility for secure, repeatable seating

Compatibility

Designed for use in Kennametal KENLOC-series toolholders accepting WNMG-style inserts. Conforms to ANSI insert code WNMG332 and ISO insert code WNMG060408. Suitable for turning, facing, and boring of steel and cast iron; secondary application on aluminum and non-ferrous materials.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing inserts. Ensure the toolholder pocket and insert seating surfaces are clean and free of chips before clamping. Verify clamp or pin torque per the toolholder manufacturer specifications rather than the insert specification — no torque value is defined by this insert alone.
