Hougen 12156 Annular Cutter 1-3/4 in Hss Weldon Shank

Product Description

The HOUGEN 12156 is a high speed steel annular cutter designed for clean, fast hole cutting in mild steel and general steel stock. With a 1-3/4 inch cutting diameter and 1 inch depth of cut, this cutter removes only a core of material rather than reducing the entire hole area to chips, making it significantly more efficient than twist drills in the same size range. The Weldon flat shank with two flats provides a secure, non-slip connection in compatible magnetic drill press chucks and arbors. At 0.45 pounds, it is a compact, easy-to-handle tool suited for fabrication shops, structural steel work, and field ironwork installations.

This cutter is intended for use in magnetic base drill presses and annular cutter-compatible drill press setups on mild steel and structural steel applications. It is a standard choice for tradespeople working in steel fabrication, mechanical contracting, and ironworking where precise, clean-edged holes are required in plate steel, tube steel, or structural members. The bright uncoated finish is appropriate for general-purpose steel cutting operations without the need for specialty coatings.

Key Features

• 1 inch depth of cut accommodates standard plate and structural stock thicknesses
• High speed steel construction provides good wear resistance for steel cutting
• Weldon flat shank with 2 flats ensures positive drive and prevents slippage in chuck
• 3/4 inch shank diameter fits standard magnetic drill press arbors and chucks
• Bright uncoated finish suitable for general-purpose mild steel and steel stock applications

Compatibility

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

Installation Notes

Annular cutters of this type are installed by licensed or qualified tradespeople using magnetic drill presses equipped with the appropriate Weldon shank chuck or arbor. Ensure the magnetic base is securely seated and energized on a clean, flat steel surface before operation. Use cutting fluid or cutting oil appropriate for high speed steel tooling to extend cutter life and improve cut quality. Inspect the Weldon flat set screws for proper engagement before each use to prevent chuck slippage.
