Sumitomo 2900W2Q Square-shoulder End Mill 3/4 in Weldon

Product Description

The SUMITOMO 2900W2Q is an indexable square-shoulder end mill designed for precision milling operations across a wide range of workpiece materials. Part of the WaveMill Series, this tool features a WEX cutter style with a Weldon flat shank and accepts AXMT12 and AXET12 insert styles secured by screw-type insert holding. With a 3/4 inch cutting diameter, a 90-degree lead angle, and through-coolant capability, it is engineered for productive square-shoulder milling in production environments. Licensed machinists and CNC tool setters are the primary users of this toolholder.

This end mill suits universal workpiece materials including cast iron, steel, non-ferrous metals, high-temperature alloys, and stainless steel, corresponding to ISO material codes K, M, N, P, and S. The WEX toolholder design supports high-feed milling applications where rigidity and insert security are critical. With a 5.091 inch overall length and a 3/4 inch Weldon shank, it is compatible with standard Weldon-style tool holders used on vertical machining centers and CNC milling machines.

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 changing this toolholder. Secure the Weldon shank using the appropriate set screw torqued per machine tool builder specifications. Verify insert seating and screw torque before initiating any cutting cycle; loose inserts can cause tool failure and workpiece damage.
