Kennametal 2425815 Turning Insert TPMT3252LF KC5025

Product Description

The KENNAMETAL 2425815 is a solid carbide turning insert carrying the industry standard designation TPMT3252LF in the KC5025 grade. Coated with TiAlN via a PVD process, this insert delivers moderate wear resistance and toughness across a broad range of workpiece materials. It features a 60-degree triangle shape with a positive rake angle of 5 degrees and a positive side clearance, making it well suited for finishing and light machining operations. The screw-on holding method provides secure clamping during interrupted and continuous cuts. Machinists and tooling technicians install and index this insert at the machine tool.

This insert is designed for turning, facing, and boring operations. Primary workpiece materials include stainless steel and superalloys and titanium, with additional suitability for steel, cast iron, aluminum, and non-ferrous materials. The LF chip breaker geometry is optimized for finishing and light machining passes, keeping chip control consistent at tighter depths of cut up to 1.25 mm. It conforms to both ANSI and ISO standards, with ANSI code TPMT3252 and ISO code TPMT16T308, making it straightforward to cross-reference in standard tooling catalogs.

Key Features

• TiAlN PVD coating provides moderate wear resistance and thermal stability across steel, stainless, cast iron, and non-ferrous applications
• LF chip breaker geometry engineered for finishing and light machining with maximum depth of cut of 1.25 mm (0.0492 inches)
• Positive rake and positive side clearance reduce cutting forces and heat generation
• Screw-on mounting method ensures repeatable insert indexing and secure seating
• Three cutting edges per insert maximize tool life per unit
• Conforms to ANSI and ISO standards for broad cross-reference compatibility

Compatibility

Designed as a screw-on turning insert conforming to ANSI insert code TPMT3252 and ISO insert code TPMT16T308, compatible with toolholders designed for TPMT-style inserts with a screw-on clamping system. Suitable for multi-use applications including turning, facing, and boring.

Installation Notes

Installation is performed by qualified machinists or tooling technicians at the machine tool. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key to seat the clamping screw without over-torquing the insert pocket. Inspect the toolholder pocket for wear or debris before seating a new insert to ensure proper support and runout.
