Hougen 12146 Annular Cutter 1-7/16 in Hss Weldon

Product Description

The HOUGEN 12146 is a high-speed steel annular cutter designed for clean, full-diameter hole cutting in mild steel and steel plate. With a cutting diameter of 1-7/16 inches (1.4375 inches decimal) and a 1 inch depth of cut, this cutter removes only the material at the hole perimeter rather than reducing the entire bore to chips. The 3/4 inch Weldon flat shank with two flats seats securely in compatible magnetic drill press arbors, preventing slippage under load. The bright, uncoated finish is standard for HSS cutters used in general fabrication work. Weighing 0.36 pounds, it is a compact tool suited for field and shop use by ironworkers, pipefitters, steel fabricators, and maintenance mechanics.

This cutter is intended for use in magnetic drill presses and drill press arbors that accept a 3/4 inch Weldon shank. It is well suited for structural steel work, metal fabrication, and mechanical maintenance applications where clean-edged holes in mild steel or steel stock are required. The annular cutting geometry produces less heat and consumes less power than twist drills of comparable diameter, making it practical for portable magnetic drill operations on beams, plates, and structural members.

Key Features

• 1-7/16 inch cutting diameter for full-diameter hole production in steel
• 1 inch depth of cut accommodates standard structural steel thicknesses
• High-speed steel construction provides durability across mild steel applications
• 3/4 inch Weldon flat shank with 2 flats locks securely in magnetic drill arbors
• Bright, uncoated finish — no coating to chip or delaminate during use
• Annular geometry reduces cutting force and heat compared to solid twist drills

Compatibility

Designed for use with magnetic drill presses and arbors accepting a 3/4 inch Weldon flat shank. Material application is rated for mild steel and steel stock.

Installation Notes

Installation and use of annular cutters should be performed by qualified tradespeople familiar with magnetic drill press operation. Ensure the magnetic drill base is fully energized and seated on a clean, flat steel surface before beginning the cut. Always use the appropriate cutting fluid or lubricant to extend tool life and manage heat buildup. Inspect the shank seating and Weldon flat engagement before each use to confirm the cutter is fully locked in the arbor.
