Hougen 12221 Annular Cutter 21/32 in Hss Weldon Shank

Product Description

The HOUGEN 12221 is a high speed steel annular cutter designed for clean, fast hole cutting in mild steel and steel plate. With a cutter diameter of 21/32 inches (0.6562 inches decimal) and a cutting depth of 2 inches, this cutter removes only a thin ring of material rather than a full slug, reducing heat buildup and extending tool life. The 3/4 inch Weldon flat shank with two flats provides positive drive engagement and prevents slippage under load. It ships in a bright, uncoated finish. This cutter is used by fabricators, ironworkers, and maintenance technicians working with magnetic drill presses.

The HOUGEN 12221 is suited for structural steel fabrication, steel erection, and general metalworking applications where clean through-holes are required in mild steel and steel stock. The 2 inch depth of cut accommodates thick plate and stacked material passes. The Weldon flat shank is the standard interface for most magnetic drill presses and rotary broaching setups used in the field and in the shop. It is a single-piece cutter, sold individually.

Key Features

• 21/32 inch cutter diameter (0.6562 inches) for precise hole sizing
• 2 inch cutting depth handles thick plate and structural sections
• High speed steel construction for durability in ferrous metal cutting
• 3/4 inch Weldon flat shank with 2 flats for positive, slip-free drive engagement
• Bright, uncoated finish suitable for standard steel cutting applications
• Annular cutting geometry reduces cutting force and chip volume compared to twist drills

Compatibility

Designed for use in magnetic drill presses and other drilling equipment accepting a 3/4 inch Weldon flat shank. Rated for use in mild steel and steel material applications.

Installation Notes

Installation and use of annular cutters should be performed by qualified metalworkers or fabricators familiar with magnetic drill press operation. Ensure the magnetic base is fully energized and seated on a clean, flat surface before beginning a cut. Use the recommended cutting fluid for the material being drilled to reduce heat and extend cutter life. Inspect the shank seating and flat engagement in the arbor before each use to confirm secure lockdown.
