Kennametal 6201292 Milling Insert KC422M Solid Carbide

Product Description

The KENNAMETAL 6201292 is a solid carbide milling insert in the LNGU series, designed for high-performance face and shoulder milling in non-ferrous metal applications. Manufactured to grade KC422M with a Titanium Diboride (TiB2) coating applied via PVD process, this rectangular insert delivers a honed cutting edge and positive rake geometry for clean, efficient material removal. It measures 0.4790 inches in length, 0.2598 inches in width, and 0.1875 inches in thickness. With four cutting edges and a right-hand orientation, it is a cost-effective choice for licensed machinists and toolroom professionals working in CNC milling operations.

This insert is suited for milling non-ferrous metals including aluminum alloys and other N-class workpiece materials. The LNGU insert style with chip breaker designation LE is optimized for light to medium cuts where surface finish and edge integrity are priorities. It is compatible with the Mill 4-11 cutter series and is held in place by a screw-type mounting system. The 0.0160-inch corner radius and 90-degree included angle make it appropriate for both roughing and finishing passes on non-ferrous workpieces in both production and job-shop environments.

Key Features

• KC422M grade solid carbide with PVD-applied Titanium Diboride (TiB2) coating for wear resistance on non-ferrous metals
• Four cutting edges per insert for extended tool life and lower cost-per-edge
• Positive rake and honed cutting edge geometry for reduced cutting forces and clean chip formation
• Corner radius of 0.0160 inches (1/64 inch) for controlled edge engagement
• Screw-type insert holding for secure, repeatable seating in compatible cutter bodies
• Meets ANSI and ISO standards; ANSI code LNGU431ERLEJ, ISO code LNGU110404ERLEJ

Compatibility

Designed for use with the Kennametal Mill 4-11 cutter series. Insert style is LNGU, size code 431. Compatible with right-hand cutter bodies configured for screw-held LNGU-style inserts in that series.

Installation Notes

Indexable carbide inserts should be installed by a qualified machinist or toolroom technician using the appropriate torx or hex key as specified by the cutter body manufacturer. Always power down and lock out the machine spindle before indexing or replacing inserts. Inspect the cutter pocket and clamping screw for wear or damage before seating a new insert. Do not use inserts that show chipping or coating delamination on any edge.
