Sumitomo 2900W2W Indexable Square-shoulder End Mill

Product Description

The SUMITOMO 2900W2W is an indexable square-shoulder end mill designed for high-performance milling operations across a wide range of workpiece materials. Built on the WaveMill WEX toolholder platform, this mill accepts AXMT17 and AXET17 insert styles and features a 90-degree lead angle for true square-shoulder cutting. The 1-inch cutting diameter pairs with a 1-inch Weldon flat shank, and through-coolant capability helps manage heat and chip evacuation at the cutting zone. With an overall length of 4.841 inches and two insert seats, this tool is suited for roughing and finishing passes in demanding shop environments. Licensed machinists and CNC tooling specialists are the primary users.

This end mill is suited for milling alloy steel, stainless steel, cast iron, aluminum alloy, and other non-ferrous metals, covering ISO material codes P, M, K, N, and S. The WEX cutter style and Weldon flat shank make it compatible with standard WEX toolholders used in vertical and horizontal machining centers. It is commonly applied in job shops, aerospace, and general manufacturing where square-shoulder profiling, slotting, and step milling are required. The through-coolant feature supports higher cutting speeds and extended insert life in difficult-to-machine materials.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or changing inserts. Secure the Weldon flat shank in a properly sized end mill holder or collet chuck to the machine manufacturer's specified torque procedure. Verify through-coolant passages are clear and that coolant pressure is within the machine tool's rated range before initiating cuts.
