Hougen 12426 Annular Cutter 1.0236 in Hss Weldon Shank

Product Description

The HOUGEN 12426 is a high speed steel annular cutter designed for fast, clean hole cutting in mild steel and general steel fabrication work. With a cutting diameter of 1.0236 inches and a cutting depth of 50 millimeters (approximately 1.97 inches), it removes only a core of material rather than reducing the entire hole area to chips. The 3/4-inch Weldon flat shank with two flats locks securely into compatible magnetic drill presses and annular cutter chucks, resisting rotation under load. The bright, uncoated finish is standard for high speed steel tooling intended for use with cutting fluid. Licensed electricians, ironworkers, pipefitters, and steel fabricators use this cutter in production and field applications.

The HOUGEN 12426 is suited for drilling clean through-holes in structural steel, plate steel, and mild steel fabrications where conventional twist drills would require excessive force or produce poor hole quality. Annular cutters of this type are standard tooling on magnetic drill presses used in steel erection, mechanical room rough-in, and HVAC equipment mounting applications. The 1.0236-inch diameter makes it appropriate for holes requiring close dimensional tolerance in plate thicknesses up to the cutter depth capacity.

Key Features

• 1.0236-inch cutting diameter for precise hole sizing in steel plate
• 50-millimeter cutting depth (approximately 1.97 inches) for full penetration of standard structural members
• High speed steel construction provides durability in ferrous metal cutting applications
• 3/4-inch Weldon flat shank with two flats for positive drive and reduced slippage in magnetic drill chucks
• Bright, uncoated finish compatible with standard cutting oils and coolants
• Annular cutting geometry reduces cutting force and chip volume compared to twist drill design

Compatibility

Designed for use with magnetic drill presses and annular cutter arbors accepting a 3/4-inch Weldon flat shank. Rated for material applications in mild steel and general steel. Verify chuck compatibility before installation.

Installation Notes

Installation and use of annular cutters should be performed by qualified tradespeople familiar with magnetic drill press operation. Secure the magnetic base fully to a clean, flat steel surface before engaging the cutter, and confirm the workpiece is clamped or fixtured as required. Always use cutting fluid or a recommended cutting oil to extend tool life and improve hole finish. Inspect the Weldon flat shank and chuck setscrew for wear before each use to ensure positive drive engagement.
