Kennametal 6132022 Milling Insert KC522M Altin LNGU432SRGE

Product Description

The KENNAMETAL 6132022 is a solid carbide milling insert in the LNGU series, grade KC522M, featuring a Physical Vapor Deposition (PVD) AlTiN coating for high heat resistance and extended tool life. The insert carries an ANSI code of LNGU432SRGE and ISO code LNGU110408SRGE. It is rectangular in shape with a positive rake geometry, a chamfered and honed cutting edge style, and a GE chip breaker. With four usable cutting edges and a 90-degree included angle, this single-sided, right-hand insert is engineered for productive milling in demanding material applications. It is sized at 3/16 inches thick and 6.5 mm (0.2598 inches) wide, with a corner radius of 0.031 inches (1/32 inch).

This insert is intended for milling operations across a broad range of workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium — material grade codes P, M, K, and S. It is compatible with the Mill 4-11 cutter series and is held in place by a screw-type insert holding method. Typical installation scenarios include face milling and shoulder milling on CNC machining centers in both production shop and job shop environments. The insert is suited for licensed machinists and tooling technicians working in metalworking and precision manufacturing applications.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before seating or replacing inserts. Secure the insert using the appropriate screw and torque driver recommended by the cutter body manufacturer. Inspect the insert pocket and seating surfaces for debris or wear before installing a fresh insert to ensure proper seating and runout.
