Kennametal 2267536 Indexable Square-shoulder End Mill

Product Description

The KENNAMETAL 2267536 is an indexable square-shoulder end mill designed for precision milling operations in metalworking and machining environments. Built on a cylindrical shank with a 1.25-inch shank diameter and a 1-1/4-inch cutting diameter, this toolholder accommodates EC18 and EP18 insert styles for repeatable cutting performance. The 0-degree lead angle promotes true square-shoulder cuts, making it well suited for shoulder milling, face milling, and step milling applications. With a maximum depth of cut of 18mm (0.71 inches) and an overall length of 8 inches, it is typically installed by machinists and CNC operators working in production or job-shop settings.

This end mill toolholder is used in vertical and horizontal CNC machining centers as well as manual milling machines where square-shoulder profiling is required. The Mill 1-18 cutter style supports 2-flute, 2-insert configurations, making it appropriate for medium to light material removal in steel, stainless, cast iron, and similar materials. It is well matched to applications where insert changeability and consistent shoulder geometry are priorities.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the cylindrical shank in a properly sized collet, end mill holder, or milling chuck before use, and verify runout with a dial indicator prior to cutting. Torque insert retaining screws to the toolholder manufacturer specification using the correct Torx or hex key. Always power down and lock out the spindle before changing inserts or adjusting the toolholder.
