Kennametal 1871000 DPMT3252LF KC5010 Turning Insert

Product Description

The KENNAMETAL 1871000 is a solid carbide turning insert with ANSI code DPMT3252 and ISO code DPMT11T308, designed for precision metal cutting in CNC turning, facing, boring, back turning, and back boring operations. It features a TiAlN coating applied via PVD process, a 55-degree diamond (rhombic) insert shape, and a KC5010 manufacturer grade known for high to moderate wear resistance and toughness across multiple workpiece materials. The insert carries a positive rake angle of 5 degrees, an 11-degree relief angle, and a honed cutting edge for a clean, controlled finish in finishing and light machining applications. It is installed and serviced by machining professionals on CNC lathes and turning centers.

This insert is suited for finishing and light machining passes on steel, stainless steel, cast iron, superalloys, titanium, and aluminum. Its LF chip breaker geometry is optimized for low cutting forces and tight chip control at light depths of cut, with a maximum depth of cut of 0.0492 inches (1.25 mm). The neutral hand orientation and screw-on holding method make it compatible with a wide range of standard DPMT-style toolholders used in both production and job-shop turning environments.

Key Features

• ANSI insert code DPMT3252, ISO code DPMT11T308 for broad toolholder compatibility
• TiAlN PVD coating provides high wear resistance across steel, stainless, cast iron, superalloys, and titanium
• 55-degree diamond shape with positive rake and positive side clearance for reduced cutting forces
• LF chip breaker geometry rated for finishing and light machining operations
• 2 cutting edges per insert; screw-on holding method for secure, repeatable seating
• Maximum depth of cut 1.25 mm (0.0492 inches); honed cutting edge for consistent surface finish

Compatibility

Designed as a screw-on replacement insert for DPMT-style toolholders conforming to ANSI and ISO standards. Suitable for primary workpiece materials coded P (steel), M (stainless steel), K (cast iron), N (aluminum and non-ferrous), and S (superalloys and titanium).

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Always power down and lock out the machine before changing inserts. Seat the insert fully against the toolholder pocket before tightening the clamping screw; do not overtighten. Verify insert orientation and toolholder clearance angles are correct for the intended operation before resuming cuts.
