Kennametal 3760457 CNMG542UP KCM35 Carbide Turning Insert

Product Description

The KENNAMETAL 3760457 is a CNMG542UP indexable turning insert in the KCM35 grade, designed for roughing and medium machining of steel, stainless steel, and superalloys including titanium. The insert is manufactured from solid carbide and features a multilayer MTCVD coating system of TiN, TiCN, and Al2O3, delivering high toughness on steel and moderate wear-resistance on stainless steel. The 80-degree diamond (rhombic) shape provides a strong cutting edge geometry. With four usable cutting edges and a neutral hand orientation, this insert suits a wide range of turning, facing, and boring operations. It is installed by qualified machinists and CNC operators in production and job-shop environments.

This insert fits into the KENLOC toolholding system and is suited for external turning, facing, and boring on CNC lathes and manual turning centers. It is well-matched for applications involving steel and stainless steel workpieces where a balance of toughness and wear-resistance is required. The UP chip breaker geometry supports both roughing passes and medium material removal rates. The negative rake and negative side clearance geometry maximize edge strength, making this insert appropriate for interrupted cuts and scaled or hardened surfaces typical in steel and stainless steel part production.

Key Features

• KCM35 grade with multilayer MTCVD coating: TiN, TiCN, and Al2O3 for toughness and wear-resistance on steel and stainless steel
• CNMG542UP geometry: 80-degree diamond shape with UP chip breaker for roughing and medium machining
• Four cutting edges with neutral hand orientation for versatile setup in turning, facing, and boring
• Negative rake and negative side clearance for maximum cutting edge strength on demanding workpiece materials
• Honed cutting edge style for consistent performance and repeatable tool life
• ANSI and ISO standardized insert code for cross-reference and toolholder compatibility

Compatibility

Designed for use in KENLOC-series toolholders accepting CNMG542 (ANSI) or CNMG160608 (ISO) inserts with clamp or pin holding methods. Suitable for turning, facing, and boring of steel (P), stainless steel (M), superalloys, and titanium workpiece materials per the KCM35 grade specification.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and KENLOC clamping hardware to secure the insert; do not overtighten the clamp screw by feel alone. Inspect the insert seat and chip pocket for debris before seating a new cutting edge to ensure proper insert contact and prevent premature edge failure.
