Kennametal 5388036 Turning Insert CNMG432MN KCP10B Carbide

Product Description

The KENNAMETAL 5388036 is a CNMG432MN turning insert in the KENLOC series, designed for general-purpose metal cutting on CNC lathes and turning centers. It features a multilayer CVD coating of TiCN, Al2O3, and TiOCN over a solid carbide substrate, providing wear resistance and thermal stability across a range of cutting conditions. The insert carries an 80-degree diamond shape, a neutral hand orientation, and a negative rake geometry with a chamfered and honed cutting edge. With an inscribed circle of 0.5 inches and a corner radius of 0.0313 inches, it is sized for medium material removal and finishing passes. The MN chip breaker geometry controls chip flow during steel and cast iron operations.

This insert is suited for turning, facing, and boring applications in both production and job-shop environments. Primary workpiece materials are steel and cast iron, corresponding to ISO material codes P and K. The CNMG432MN geometry is a widely used standard in industrial turning, making this insert a practical choice for licensed machinists and toolroom technicians running medium-duty cutting programs. The KENLOC series is engineered for use with compatible toolholders that accept clamp-and-pin insert holding methods.

Key Features

• Multilayer CVD coating: TiCN base, Al2O3 mid-layer, TiOCN top layer for extended tool life in steel and cast iron
• 80-degree diamond insert shape (CNMG style) with negative rake for strong cutting edge
• MN chip breaker geometry for controlled chip evacuation
• Four usable cutting edges per insert, maximizing cost efficiency
• Chamfered and honed cutting edge style reduces micro-chipping at entry
• Compatible with clamp and pin holding methods in KENLOC-series toolholders
• Meets ANSI and ISO dimensional standards; ISO code CNMG120408MN

Compatibility

Designed for use in KENLOC-series toolholders that accept CNMG-style inserts with clamp and pin holding. Suitable for turning, facing, and boring of steel and cast iron workpieces. Conforms to ANSI and ISO standards for CNMG432MN geometry.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer when tightening the clamp screw — do not overtighten. Inspect the insert seat and clamp pin for wear or debris before installing a new insert to ensure proper seating and runout control.
