Hougen 12164 Annular Cutter 2in Hss Weldon Shank

Product Description

The HOUGEN 12164 is a high speed steel annular cutter designed for fast, clean through-holes in mild steel and steel plate. It cuts a 2-inch diameter hole to a depth of 1 inch, removing only a core of material rather than a full slug, which reduces heat buildup and extends cutter life compared to standard twist drills. The 3/4-inch Weldon flat shank with two flats locks securely into compatible magnetic drill press chucks and annular cutter arbors, preventing slippage under load. The bright, uncoated finish is standard for HSS tooling used in general-purpose steel fabrication and structural work.

This cutter is suited for structural steel fabrication, ironwork, mechanical contracting, and maintenance applications where accurate, burr-minimized holes are required in mild steel or steel plate. It is well matched to portable magnetic drills and benchtop drill press setups equipped with a 3/4-inch Weldon-style chuck or arbor adapter. Typical users include ironworkers, millwrights, mechanical contractors, and maintenance technicians working on structural connections, equipment frames, and pipe supports.

Key Features

• 2-inch cutting diameter for full-size through-holes in a single pass
• 1-inch depth of cut accommodates standard structural steel thicknesses
• High speed steel construction provides durability in mild steel and general steel applications
• 3/4-inch Weldon flat shank with 2 flats for positive chuck engagement and no slippage
• Bright, uncoated finish — ready to use out of the box for standard steel cutting
• Annular cutting geometry removes only the core slug, reducing cutting force and motor load

Compatibility

Designed for use with magnetic drill presses and drill press arbors accepting a 3/4-inch Weldon flat shank. Material application includes mild steel and steel. Verify chuck or arbor compatibility before installation.

Installation Notes

Installation and operation should be performed by qualified metalworking or mechanical trade professionals familiar with magnetic drill press operation. Secure the magnetic drill base fully to a clean, flat steel surface before engaging the cutter, and verify the workpiece is clamped or otherwise restrained. Use cutting fluid or lubricant appropriate for HSS tooling in steel to maximize cutter life and cut quality. Inspect the shank seating in the Weldon chuck before each use to confirm the set screws are fully engaged against the flats.
