Kennametal 3753293 Turning Insert CNMG544RN KCP10 Carbide

Product Description

The KENNAMETAL 3753293 is a CNMG544RN-geometry solid carbide turning insert in the KCP10 grade, designed for high-productivity metal removal on steel and cast iron. The insert features a multilayer MTCVD coating consisting of TiCN and Al2O3, delivering high wear resistance against steel workpieces and moderate wear resistance with toughness on aluminum and non-ferrous materials. With an 80-degree diamond (rhombic) shape, a 5/8-inch inscribed circle, and a 1/16-inch corner radius, this insert is built for the KENLOC clamping system and is suited for roughing and medium machining operations. Licensed machinists and CNC turning specialists install this insert in production and job-shop environments.

This insert is engineered for turning, facing, and boring applications on steel and cast iron workpieces. The RN chip breaker geometry supports both roughing and medium machining passes, making it effective across a range of stock removal scenarios. The neutral hand orientation gives it flexibility across multiple toolholder setups. It carries four usable cutting edges, improving cost-per-edge economics in high-volume production runs where insert longevity and consistent surface finish are priorities.

Key Features

• MTCVD multilayer TiCN and Al2O3 coating for high wear resistance on steel and durability on non-ferrous materials
• 80-degree diamond insert shape (CNMG) with negative rake and negative side clearance for rigid, stable cutting
• RN chip breaker designed for roughing and medium machining operations
• Four cutting edges per insert for improved cost efficiency
• Compatible with clamp and pin insert holding methods
• Chamfered and honed cutting edge style for edge strength and reduced chipping risk
• Compliant with both ANSI and ISO standards (ANSI: CNMG544, ISO: CNMG160616)

Compatibility

Designed for use in KENLOC-series toolholders that accept CNMG544 (ANSI) or CNMG160616 (ISO) geometry inserts with clamp or pin holding. Suitable for turning, facing, and boring of steel and cast iron workpieces where the KCP10 grade is specified.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before seating or replacing inserts. Ensure the toolholder pocket and clamping components are clean and free of chips before installing. Verify torque on clamping screws per toolholder manufacturer specifications, and confirm insert seating before resuming cutting operations.
