Kennametal 2479512 Indexable Square-shoulder End Mill

Product Description

The KENNAMETAL 2479512 is an indexable square-shoulder end mill designed for precision milling operations in metalworking and machining applications. Built on a Weldon flat shank, this toolholder accepts EC14.. and EP14.. insert styles and delivers a 1-1/4 inch cutting diameter with a maximum depth of cut of 0.571 inches. With a 0-degree lead angle and through-coolant capability, it supports aggressive material removal while maintaining thermal control at the cutting zone. Licensed machinists and CNC operators working in production or job-shop environments will find this tool suited to demanding square-shoulder milling work.

This end mill is configured as a Mill 1 cutter style and is intended for square-shoulder milling on ferrous and non-ferrous materials in both horizontal and vertical machining center setups. The 1 inch shank diameter and Weldon flat interface provide secure tool retention in standard milling chucks and holders. With 4 flutes and 4 cutter insert positions, it delivers balanced cutting performance across a range of feed and speed conditions. The maximum spindle speed rating of 33,400 RPM allows use on high-speed machining centers where surface finish and cycle time are critical.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully powered down and locked out before mounting or removing the toolholder. Verify insert seating and screw torque per the insert manufacturer guidelines before initiating a cut. Confirm through-coolant passages are clear and coolant supply is connected before running at elevated spindle speeds.
