Kennametal 2479507 Indexable Square-shoulder End Mill

Product Description

The KENNAMETAL 2479507 is an indexable square-shoulder end mill designed for precision milling operations in metal-cutting applications. Built around a Weldon flat shank with a 3/4 inch shank diameter, this tool accepts EC14.. and EP14.. insert styles secured by screw-style insert holding. It runs a 1 inch cutting diameter with a maximum depth of cut of 0.575 inches and an overall length of 3.78 inches. With 3 flutes and a 0-degree lead angle, it delivers clean 90-degree shoulder profiles. Through-coolant capability supports heat management at elevated spindle speeds up to 39,200 RPM. Licensed machinists and CNC operators working in job shop and production environments are the primary users of this toolholder.

This end mill is suited for square-shoulder milling in ferrous and non-ferrous materials where a true 90-degree wall is required. The Weldon flat shank provides positive drive retention in standard end mill holders. At a head length of 1.75 inches and a maximum speed of 39,200 RPM, it fits high-speed machining center setups common in precision part manufacturing, aerospace component work, and general metalworking production. The through-coolant channel supports chip evacuation and tool life in deep-shoulder and slotting passes.
