Sumitomo 2900W2T Indexable Square Shoulder End Mill

Product Description

The SUMITOMO 2900W2T is an indexable square-shoulder end mill designed for high-precision milling operations across a wide range of workpiece materials. Built on the WaveMill series platform with a WEX cutter style, this toolholder accepts AX.T 12350 insert style inserts 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 for positive rotational engagement in the spindle. Through-coolant capability supports chip evacuation and thermal management during aggressive cuts. Licensed machinists and CNC setup technicians are the primary installers.

The 2900W2T suits universal workpiece material classifications including ISO material codes K, M, N, P, and S, making it adaptable across cast iron, non-ferrous alloys, steel, stainless, and superalloys. Its four-insert configuration provides balanced cutting forces and productivity in face milling, shoulder milling, and step machining applications on vertical and horizontal machining centers. The overall assembly length of 3.811 inches and a head length of 1.530 inches support use in standard tool assemblies without extended-reach considerations.

Compatibility

Designed for use with AX.T 12350 style inserts. ISO toolholder number WEX21000EW. Compatible with machining centers equipped to accept a 1-inch Weldon flat shank. Refer to SUMITOMO WaveMill series insert selection documentation for insert grade and geometry recommendations by material code.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician following the machine tool manufacturer's toolholder retention specifications. Ensure the spindle is fully stopped and the machine is in a safe locked-out state before mounting or removing the toolholder. Verify set-screw torque to the Weldon flat per shop standards and confirm through-coolant passages are clear and unobstructed before resuming operation. Follow applicable shop safety protocols for indexable insert handling, as insert edges are sharp.
