Kennametal 1024930 Square-shoulder Face Mill 3 in Kssm

Product Description

The KENNAMETAL 1024930 is an indexable square-shoulder face mill designed for precision milling of flat surfaces and 90-degree shoulders in ferrous and non-ferrous workpiece materials. The body accepts four SD.T 43.. style inserts secured by screw-lock retention and delivers a maximum cutting diameter of 3 inches with a maximum depth of cut of 0.361 inches. The 1-inch arbor hole provides a secure machine spindle connection, and the right-hand cutting direction suits standard vertical and horizontal milling center setups. Licensed machinists and toolroom professionals install and configure this cutter as part of a modular insert tooling program.

The 1024930 belongs to the KENNAMETAL KSSM series, which targets coarse-pitch square-shoulder face milling applications. Its 0/90 lead angle produces true 90-degree walls, making it appropriate for step milling, shoulder profiling, and face finishing operations in job shop, production machining, and maintenance-repair environments. The cutter body measures 1.75 inches in overall height with a maximum body diameter of 2.953 inches and a hub diameter of 2.065 inches, fitting standard milling machines and machining centers that accept a 1-inch arbor mount.
