Kennametal 5388031 Turning Insert CCMT32.51 KCP10B Carbide

Product Description

The KENNAMETAL 5388031 is a CCMT-style indexable turning insert designed for precision material removal on steel and cast iron workpieces. It carries the KCP10B manufacturer grade and features a multilayer CVD coating system of TiCN, Al2O3, and TiOCN applied via MTCVD process, delivering thermal resistance and wear protection across a range of cutting conditions. The insert has an 80-degree diamond shape, a neutral hand orientation, and a honed cutting edge. With a 3/8-inch inscribed circle, a 1/64-inch corner radius, and an insert thickness of 5/32 inch, it fits standard CCMT screw-on toolholders. Two cutting edges are available per insert.

This insert is suited for turning, facing, and boring operations in ISO material groups P (steel) and K (cast iron). It is appropriate for both roughing and finishing passes within its rated depth of cut and is commonly used in CNC turning centers and manual lathes in production and job-shop environments. The LF chip breaker geometry is optimized for controlled chip formation, making it a practical choice for continuous and interrupted cuts on ferrous materials. Machinists and tooling technicians working in general metalworking, aerospace component machining, and repair shops will find this insert a direct-fit solution for standard CCMT tooling setups.

Key Features

• KCP10B grade with multilayer CVD coating: TiCN, Al2O3, and TiOCN for extended tool life on ferrous materials
• 80-degree diamond insert shape (CCMT) with 7-degree relief angle and 5-degree positive rake angle
• LF chip breaker geometry for reliable chip control in turning, facing, and boring applications
• Honed cutting edge style reduces chipping risk at the cutting edge
• Screw-on holding method provides secure seating and repeatable insert indexing
• Two usable cutting edges per insert for cost-effective tooling consumption
• Meets ANSI and ISO standards; ISO code CCMT32.51

Compatibility

Designed for use in standard CCMT screw-on indexable toolholders rated for 3/8-inch inscribed circle inserts. Primary workpiece materials are steel (ISO P) and cast iron (ISO K). Suitable for turning, facing, and boring operations per manufacturer specifications.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct torx or hex key to torque the clamping screw to the toolholder manufacturer specification — do not over-tighten or use impact drivers on insert screws. Verify insert seating and pocket cleanliness before resuming cutting operations.
