Sumitomo 2900W6L Indexable Square-shoulder End Mill 3/4in

Product Description

The SUMITOMO 2900W6L is an indexable square-shoulder end mill designed for precision milling operations in metal cutting applications. Built on the WEZ platform, this tool accepts AOMT11 and AOET11 inserts and is constructed from steel with a Weldon shank for secure, anti-rotation clamping in standard milling chucks. It carries a 3/4 inch cutting diameter, a maximum depth of cut of 0.394 inches, and an overall length of 3.563 inches. A 90-degree lead angle produces true square shoulders, making it well suited for step milling, slotting, and face milling passes where wall perpendicularity matters. Coolant-through capability supports chip evacuation and tool life in demanding cuts.

This end mill is intended for use in CNC vertical and horizontal machining centers as well as manual knee mills equipped with compatible Weldon-shank toolholders. The 3-insert configuration and right-hand cut orientation make it a standard production choice for shops machining ferrous and non-ferrous workpieces requiring square-shoulder profiles. It is sized for mid-range spindle platforms common in job shop and production floor environments. Setup involves seating the Weldon shank in a matching bore holder and securing the set screw against the flat before running the tool at manufacturer-recommended speeds and feeds for the chosen insert grade.

Compatibility

Accepts AOMT11 and AOET11 series indexable inserts. Designed for use with Weldon-shank toolholders sized for a 3/4 inch shank bore. Also cataloged under manufacturer number WEZ20750EW03.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered off and the spindle fully stopped. Seat the Weldon shank fully into the holder bore and tighten the set screw against the flat to the holder manufacturer's specified torque before operation. Inspect each indexable insert for chips or seating irregularities before running. Follow the insert manufacturer's recommended cutting data for the specific insert grade and workpiece material selected.
