Kennametal 2425785 Turning Insert CPMT3252LF KC5025

Product Description

The KENNAMETAL 2425785 is a solid carbide turning insert in the CPMT3252LF geometry with KC5025 grade, designed for precision metal-cutting operations on CNC and manual turning equipment. The insert features a TiAlN coating applied via PVD process, providing moderate wear resistance and toughness across a wide range of workpiece materials. The 80-degree diamond (rhombic) shape with a positive rake angle and honed cutting edge style makes this insert well suited for finishing and light machining passes. With a 3/8-inch inscribed circle and a 1/32-inch corner radius, it is engineered to maintain dimensional accuracy and surface finish in demanding turning environments.

This insert is intended for turning, facing, and boring operations on stainless steel, carbon and alloy steels, cast iron, aluminum and non-ferrous materials, and superalloys including titanium. The LF chip breaker geometry targets finishing and light machining cuts with a maximum depth of cut of 1.25 mm (0.0492 inches). The neutral hand orientation and screw-on mounting method make it compatible with standard CPMT-style toolholders. Licensed tradespeople and machinists working in job shops, production machining, and aerospace or industrial manufacturing environments are the primary installers.

Key Features

• KC5025 grade with PVD TiAlN coating for moderate wear resistance and toughness across steel, stainless, cast iron, aluminum, and superalloy workpieces
• 80-degree diamond (rhombic) insert shape with positive rake and positive side clearance for clean shearing action
• LF chip breaker optimized for finishing and light machining operations
• Screw-on holding method with two available cutting edges per insert
• Honed cutting edge style reduces microchipping on interrupted or work-hardened surfaces
• Complies with ANSI (CPMT3252) and ISO (CPMT09T308) insert standards for broad toolholder compatibility

Compatibility

Designed to seat in screw-on CPMT-style toolholders conforming to ANSI insert code CPMT3252 and ISO insert code CPMT09T308. Suitable for multi-use applications including turning, facing, and boring across steel (P), stainless steel (M), cast iron (K), aluminum and non-ferrous (N), and superalloys and titanium (S) workpiece material categories.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and all stored energy dissipated before changing inserts. Seat the insert firmly against the pocket walls and torque the clamping screw according to the toolholder manufacturer specifications. Inspect the insert pocket and clamping hardware for wear or debris before seating a new insert. Follow shop safety protocols and applicable OSHA machine-guarding requirements when servicing cutting tools.
