Kennametal 5544406 Square-shoulder Face Mill 3 in

Product Description

The KENNAMETAL 5544406 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining applications. With a 3-inch maximum cutting diameter and a 1-inch arbor hole, this cutter accepts seven LNGU15T608SRGE inserts secured by a clamp and screw holding method. The 0-degree lead angle allows for true 90-degree shoulder milling, making it well-suited for producing flat surfaces with accurate step features. Part of the MILL 4-15 series, this tool is installed and operated by machinists and tooling professionals in CNC and manual milling setups.

This face mill is used in industrial machining environments where square-shoulder milling of ferrous and non-ferrous metals is required. Its 15.5 mm maximum depth of cut and 44.45 mm overall height accommodate a range of roughing and semi-finishing passes on vertical and horizontal milling machines. The 1-inch arbor interface provides a rigid, stable connection to standard milling spindles commonly found in job shop and production environments.

Installation Notes

Installation and setup should be performed by qualified machinists or tooling technicians familiar with milling cutter assemblies. Ensure the machine spindle is fully powered down and locked out before mounting or demounting the cutter. Verify arbor and spindle interfaces are clean and free of debris before assembly. Follow the machine tool manufacturer guidelines for clamping torque and runout inspection before initiating a cutting pass.
