Kennametal 5413188 Turning Insert CPMT32.52MF KCP25B

Product Description

The KENNAMETAL 5413188 is a solid carbide turning insert designated CPMT32.52MF in the KCP25B grade, designed for precision metal-cutting operations on CNC lathes and turning centers. It carries a multilayer CVD coating — TiCN, Al2O3, and TiOCN — applied via MTCVD process, providing moderate wear resistance and toughness suited to steel, cast iron, aluminum, and other non-ferrous materials. The insert features an 80-degree diamond (rhombic) shape, a positive rake geometry, a 1/32 inch corner radius, and an inscribed circle of 3/8 inch. The MF chip breaker designation targets finishing and medium machining operations where controlled chip formation and surface finish are priorities. Screw-on holding method ensures secure seating in compatible toolholders.

This insert is applied in turning, facing, and boring operations on CNC and manual lathes across job shop, production, and maintenance machining environments. It is suited for work on steel and cast iron as primary workpiece materials, as well as aluminum and non-ferrous alloys where the KCP25B grade provides adequate toughness and wear resistance. With two cutting edges per insert and a neutral hand designation, it fits a wide range of screw-on toolholder setups. Typical users include CNC machinists, tool-and-die shops, and industrial maintenance teams performing precision turning work.

Key Features

• 80-degree diamond (C-shape) insert geometry with positive rake and positive side clearance
• MF chip breaker optimized for finishing and medium machining operations
• 1/32 inch corner radius with chamfered and honed cutting edge style
• Two usable cutting edges per insert; screw-on mounting method
• Conforms to ANSI insert code CPMT3252 and ISO insert code CPMT09T308

Compatibility

Designed for use in screw-on toolholders accepting CPMT-style inserts per ANSI code CPMT3252 and ISO code CPMT09T308. Compatible applications include turning, facing, and boring on steel, cast iron, aluminum, and non-ferrous workpieces. Multi-use tool rated for use across these operations per manufacturer data.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the pocket and secure with the appropriate screw torque using the toolholder manufacturer's specified driver — do not over-torque the clamping screw. Inspect the insert pocket and screw threads for wear or debris before seating a new insert to maintain accurate positioning and surface finish results.
