Kennametal 5544403 Square-shoulder Face Mill 2 in

Product Description

The KENNAMETAL 5544403 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining applications. With a 2-inch maximum cutting diameter and a 3/4-inch arbor hole diameter, this mill accepts five LNGU15T608SRGE-style inserts secured by a clamp and screw holding method. The maximum depth of cut reaches 15.5 mm (0.61 inches), and the overall tool height is 40.01 mm (1.575 inches). The 0-degree lead angle promotes clean, square shoulders on workpieces. Machinists and tool-and-die professionals install this unit on CNC machining centers and manual knee mills where controlled face milling and shoulder work are required.

This face mill is suited for light to medium material removal on steel, cast iron, and similar ferrous materials in both production and job-shop environments. The MILL 4-15 series designation identifies it within KENNAMETAL's modular milling platform, making it a recognized tool body for shops already running compatible insert inventories. It fits standard arbor-mount spindles with a 3/4-inch bore and is appropriate for horizontal or vertical machining center setups where square-shoulder profiles are specified.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Disengage and lock out the machine spindle completely before mounting or removing the tool body or changing inserts. Use a properly sized arbor and appropriate torque equipment per the machine tool manufacturer's specifications when securing the mill to the spindle. Inspect insert seats and clamping hardware for wear or debris before each use to ensure secure insert retention during cutting.
