Kennametal 3758784 CNMG432FP KCM15 Turning Insert Carbide

Product Description

The KENNAMETAL 3758784 is a CNMG432FP-style solid carbide turning insert in the KCM15 grade, designed for high-productivity metal cutting on CNC lathes and turning centers. The insert features a multilayer MTCVD coating combining TiCN and Al2O3 for wear resistance and thermal stability during continuous and interrupted cuts. It carries an 80-degree diamond shape, a neutral hand orientation, and a negative rake geometry with a 15-degree rake angle. With a 0.5 inch inscribed circle, a 0.1875 inch thickness, and a 0.0313 inch corner radius, this insert is engineered for rigidity and consistent chip control through its FP chip breaker. Honed cutting edges reduce built-up edge and extend tool life in demanding applications.

The 3758784 is suited for turning, facing, and boring operations on steel, stainless steel, superalloys, and titanium workpieces. It is a direct fit for KENLOC-series toolholders that accept CNMG432 inserts with clamp-and-pin holding. The four available cutting edges make it a cost-effective choice for production turning environments in both job shop and high-volume manufacturing settings. Licensed machinists and CNC operators working to ANSI and ISO tooling standards will find the insert dimensionally consistent with industry-standard CNMG geometry.

Key Features

• MTCVD multilayer TiCN and Al2O3 coating for thermal and abrasion resistance
• FP chip breaker geometry for controlled chip evacuation on steel and stainless steel
• 80-degree diamond insert shape with negative rake for strong cutting edge support
• Four usable cutting edges per insert for extended service life
• Honed cutting edge style reduces built-up edge and micro-chipping
• Compatible with clamp-and-pin KENLOC toolholder holding systems

Compatibility

Designed for use in KENLOC-series toolholders accepting CNMG432 inserts with clamp-and-pin holding. Suitable for turning, facing, and boring of steel, stainless steel, superalloys, and titanium per primary workpiece material codes P, M, and S.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder is removed or locked before indexing or replacing inserts. Use the appropriate torque-limiting screwdriver for the clamp screw as specified by the toolholder manufacturer - do not use impact tools. Inspect the insert seat and clamp pin for wear or debris before seating a new insert to ensure proper clamping force and edge alignment.
