Kennametal 1181487 Milling Insert XPMT150412L KC725M

Product Description

The KENNAMETAL 1181487 is a solid carbide milling insert carrying the ISO designation XPMT150412L and manufactured to Kennametal grade KC725M. It features a three-layer PVD coating of TiN, TiCN, and TiN that improves wear resistance and edge stability during interrupted and continuous milling operations. The insert is parallelogram-shaped with a left-hand cutting orientation, an included angle of 88 degrees, and a corner radius of 0.0472 inches (1.20 mm). With a maximum depth of cut of 0.375 inches, it is designed for use by machinists and tool-and-die technicians on CNC and manual milling equipment in production and job-shop environments.

This insert is suited for milling steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P, M, and S. It fits applications where a left-hand, screw-held, single-sided insert is required. The KC725M grade and PVD coating process make it appropriate for moderate to demanding cutting conditions on difficult-to-machine alloys, including nickel-based superalloys and titanium workpieces common in aerospace and energy sector machining.

Key Features

• Solid carbide substrate with three-layer PVD coating: TiN / TiCN / TiN for enhanced wear resistance
• Left-hand cutting orientation, XPMT parallelogram insert style
• Corner radius of 0.0472 inches (1.20 mm) for controlled surface finish and edge strength
• Maximum depth of cut of 0.375 inches
• Screw-held, single-sided insert design for positive clamping and repeatable indexing
• Covers ISO material grades P, M, and S: steel, stainless steel, superalloys, and titanium

Compatibility

Designed for use in milling toolholders and cutter bodies that accept XPMT150412L-style inserts with a screw-mount clamping method. Verify toolholder pocket geometry, insert hand orientation (left), and seat dimensions against the XPMT 150412 insert size code before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or indexing any insert. Use the correct torque driver and insert screw specified by the toolholder manufacturer — do not overtighten, as solid carbide inserts are brittle and can crack under excess clamping force. Inspect the insert pocket and seating surface for chips or debris before installation to ensure full, flat contact.
