Hougen 12138 Annular Cutter 1-3/16 in Hss Weldon Shank

Product Description

The HOUGEN 12138 is a high speed steel annular cutter designed for clean, fast hole cutting in mild steel and steel plate. With a 1-3/16 inch cutting diameter and a 1 inch depth of cut, this cutter removes only a core of material rather than grinding out the full hole, reducing heat buildup and extending tool life compared to twist drills. The 3/4 inch Weldon flat shank with two flats provides a positive, slip-resistant connection to compatible magnetic drill presses and annular cutter chucks. The bright uncoated finish is standard for high speed steel cutters used in general fabrication and structural work. Licensed electricians, ironworkers, pipefitters, and maintenance mechanics are the primary users of annular cutters in the field and shop.

The HOUGEN 12138 is suited for drilling through mild steel and structural steel in fabrication shops, construction sites, and mechanical rooms. It is a common choice when a magnetic drill press is used to produce clean, burr-minimized holes in steel members, tube, plate, and angle iron. The 1 inch depth of cut accommodates most standard plate and structural steel thicknesses encountered in trade work. This cutter is sold individually and is appropriate for both production and occasional use applications.

Key Features

• 1-3/16 inch cutting diameter for precision hole sizing in steel
• 1 inch depth of cut handles standard structural steel plate thicknesses
• High speed steel construction provides durability in ferrous materials
• Weldon flat shank with two flats prevents rotation and slippage in the chuck
• 3/4 inch shank diameter fits standard magnetic drill press chucks
• Bright uncoated finish — no coating to flake or interfere with dimensional tolerance

Compatibility

Designed for use with magnetic drill presses and annular cutter holders accepting a 3/4 inch Weldon flat shank. Material application includes mild steel and steel. Verify chuck compatibility before installation.

Installation Notes

Annular cutters are installed and serviced by machinists, fabricators, ironworkers, and maintenance mechanics using magnetic drill presses or drill press machines with compatible Weldon-style chucks. Ensure the drill press is powered off and unplugged before changing cutters. Seat the shank fully into the chuck and tighten the set screw against the Weldon flat to prevent axial pullout during cutting. Always use cutting fluid appropriate for steel to reduce heat and extend cutter life.
