Ingersoll Cutting Tools 3031339 Square-shoulder End Mill

Product Description

The INGERSOLL CUTTING TOOLS 3031339 is an indexable square-shoulder end mill designed for facing, shouldering, and ramping operations on a wide range of workpiece materials. Built on the 1TJ1Q-1001780R01 cutter platform, it features a 1-inch Weldon Flat shank, 2 helical flutes, and a 90-degree lead angle that produces true square shoulders in a single pass. Through-coolant capability keeps cutting temperatures controlled during extended runs. The body is constructed from steel and accepts two ANxU1206 series inserts secured by screw-style retention. Maximum depth of cut is 10.92 mm (0.43 inches), making this tool well suited for moderate-depth shoulder milling at general-purpose feed and speed parameters.

This end mill fits standard CNC machining centers and manual mills equipped with a Weldon Flat toolholder in 1-inch bore. Its general-purpose, universal workpiece material rating means it performs across steel, stainless, cast iron, aluminum, and similar materials without requiring a dedicated grade body. The right-hand cutting orientation and negative rake insert geometry are standard for indexable square-shoulder tooling in production and job-shop environments. Machinists and CNC operators working on prismatic parts, pockets, and stepped features will find the 4-inch overall length gives adequate reach without excessive overhang.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator.
