Hougen 3-12244 Annular Cutter 1-3/8 in Hss

Product Description

The HOUGEN 3-12244 is a high speed steel annular cutter designed for fast, clean through-holes in mild steel and structural steel. Unlike twist drills, annular cutters remove only a ring of material, reducing the force required and extending tool life. The 3-12244 features a 1-3/8 inch cutting diameter and a 3 inch depth of cut, making it suited for thick plate and deep-hole applications. The Weldon flat shank with two flats locks securely into compatible magnetic drill press chucks and arbors, preventing slippage under load. The bright uncoated finish is standard for HSS annular cutters used across fabrication, ironwork, and structural steel trades.

This cutter is used in metalworking and fabrication environments where clean, burr-minimized holes are required in mild steel and steel plate. Typical applications include structural steel fabrication, pipe fitting layout, beam drilling, and on-site steel erection work. The 3 inch depth of cut makes it practical for heavy wall sections and stacked material. It is installed and operated by ironworkers, pipefitters, millwrights, and metal fabricators using magnetic drill presses or drill press machines with compatible Weldon-style arbors.

Compatibility

Designed for use in magnetic drill presses and drill press machines equipped with Weldon-style arbors accepting a 3/4 inch shank. Material application includes mild steel and steel plate.

Installation Notes

Installation and operation should be performed by qualified metalworkers or fabricators familiar with magnetic drill press equipment. Secure the cutter fully into the Weldon arbor, ensuring the set screws engage both flats before use. Always use cutting fluid or pilot pin lubricant when drilling to extend cutter life and reduce heat buildup. Power down and de-energize the drill press before changing cutters.
