Kennametal 5544402 Square-shoulder Face Mill 1.5in 5 Insert

Product Description

The KENNAMETAL 5544402 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining environments. Built around the MILL 4-15 series platform, it accepts five LNGU15T608SRGE inserts held in place by clamp and screw retention for reliable cutting stability. The mill features a 1.5-inch (38.10 mm) maximum cutting diameter with a 0.5-inch (12.70 mm) arbor hole for straightforward spindle mounting. A zero-degree lead angle enables true 90-degree shoulder milling, making it well-suited for step milling, shoulder profiling, and face milling applications requiring square wall geometry. Maximum depth of cut reaches 15.50 mm (0.610 inches).

This face mill is intended for use on CNC machining centers and manual milling machines in production and job-shop settings. It fits applications where tight shoulder angles and consistent surface finish are required on ferrous and non-ferrous workpiece materials. The MILL 4-15 series platform is a recognized system among tooling technicians working in aerospace, mold and die, and general metal fabrication. The 5-insert configuration and compact 1.5-inch diameter make it appropriate for smaller-diameter cuts where rigidity and insert density are priorities.

Installation Notes

Installation is performed by qualified machining technicians or toolroom personnel. Shut down and lock out the machine spindle before mounting or changing inserts. Verify arbor and spindle interface fit before tightening. Follow the machine tool manufacturer torque guidelines for drawbar and arbor retention hardware, and inspect all insert seats for debris before seating new inserts.
