Kennametal 3326926 Indexable Face Mill 4 in Kshr

Product Description

The KENNAMETAL 3326926 is a 4-inch indexable chamfer angle face mill designed for high-efficiency face milling operations in industrial machining environments. Built around the KSHR series cutter style, it accepts 8 HNGJ 535-GD inserts secured by screw-type insert holders and cuts in a right-hand direction. The arbor hole measures 1-1/4 inches in diameter, and the maximum depth of cut reaches 4.51 mm (0.178 inches). Through-coolant capability is integrated into the body, supporting extended tool life during demanding cuts. Licensed machinists and CNC operators working in metalworking shops and manufacturing facilities are the primary users of this tool.

This face mill is well suited for chamfering and face milling applications on ferrous and non-ferrous workpieces in production machining settings. Its coarse pitch configuration and 8-flute design make it effective for roughing and semi-finishing passes where high metal removal rates are needed. The KSHR series platform is intended for arbor-mount spindle setups in both horizontal and vertical machining centers running at speeds up to 6,300 RPM.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before mounting or removing the face mill from the arbor. Verify that insert pockets are clean and free of debris before seating inserts, and confirm screw torque is applied per the toolholder manufacturer guidelines. Through-coolant lines should be checked for proper flow and alignment after mounting.
