Hougen 12250 Annular Cutter 1-9/16 in Hss Weldon

Product Description

The HOUGEN 12250 is a high speed steel annular cutter designed for clean, efficient hole cutting in mild steel and steel plate. With a cutter diameter of 1-9/16 inches (1.5625 inches decimal) and a cutting depth of 2 inches, this cutter removes only a core of material rather than reducing the entire hole to chips, resulting in faster cuts and lower horsepower demand compared to twist drills. The 3/4-inch Weldon flat shank with two flats provides a secure, slip-resistant connection to compatible magnetic drill press arbors. The bright, uncoated finish suits general-purpose steel fabrication work.

This annular cutter is suited for structural steel fabrication, ironwork, and metalworking applications in both shop and field environments. Typical use cases include drilling bolt holes and conduit clearance holes in steel beams, plates, and structural sections. It is installed on magnetic drill presses or drill press arbors configured for Weldon-style shank cutters. Trade professionals including ironworkers, pipefitters, and metal fabricators commonly use this cutter for production and maintenance drilling in mild steel.

Key Features

• 1-9/16 inch (1.5625 inch) cutter diameter for consistent, accurate hole sizing
• 2-inch cutting depth accommodates thick structural steel sections
• High speed steel construction provides durability in steel cutting applications
• Weldon flat shank with two flats resists rotation and pullout in the arbor
• 3/4-inch shank diameter fits standard magnetic drill arbors with Weldon connection
• Bright, uncoated finish — no additional surface treatment to affect dimensional tolerances

Compatibility

Designed for use with magnetic drill presses and drill press arbors that accept a 3/4-inch Weldon flat shank connection. Suitable for cutting mild steel and steel stock.

Installation Notes

Installation and operation should be performed by qualified metalworking or fabrication tradespeople familiar with magnetic drill press equipment. Before mounting or changing cutters, confirm the drill press is powered off and the magnetic base is disengaged. Secure the Weldon shank fully into the arbor and tighten all set screws against the flats before operation. Always use cutting fluid or lubricant appropriate for steel to extend cutter life and improve cut quality.
