Hougen 12270 Annular Cutter 2-3/16 in Hss Weldon Shank

Product Description

The HOUGEN 12270 is a high speed steel annular cutter designed for clean, fast through-holes in mild steel and general steel stock. With a cutter diameter of 2-3/16 inches (2.1875 inches decimal) and a cutting depth of 2 inches, it handles larger-diameter hole applications where twist drills are impractical or inefficient. The 3/4-inch Weldon flat shank with two flats provides positive drive engagement, preventing slippage under load. The bright, uncoated finish is standard for high speed steel cutters intended for use with cutting fluid. Fabricators, ironworkers, and maintenance machinists are the primary installers of this tooling.

This cutter is suited for structural steel fabrication, steel plate work, beam drilling, and general metal fabrication where a 2-3/16-inch diameter hole is required. The 2-inch depth of cut allows it to pass through standard structural members and plate stock. It is used with magnetic drill presses and drill press setups equipped with a 3/4-inch Weldon-style chuck or arbor. Material applications include mild steel and general steel, making it a practical choice for field and shop work.

Installation Notes

Installation and use should be performed by qualified machinists or fabricators familiar with annular cutter tooling. Ensure the magnetic drill press or drill press spindle is fully powered down and locked out before mounting or removing the cutter. Secure the Weldon flat shank firmly in the chuck with set screws seated against both flats before operation. Always apply appropriate cutting fluid during use to maintain cutter life and surface finish quality.
