Hougen 12160 Annular Cutter 1-7/8 in Hss Weldon Shank

Product Description

The HOUGEN 12160 is a high speed steel annular cutter designed for cutting clean, precise holes in mild steel and steel plate. With a cutter diameter of 1.875 inches and a 1 inch depth of cut, it removes only a core of material rather than reducing the entire hole to chips, which reduces heat buildup and extends tool life compared to twist drills. The 3/4 inch Weldon flat shank with two flats provides positive drive engagement and prevents slippage under load. This cutter is used by ironworkers, fabricators, pipefitters, and millwrights working with magnetic drill presses and annular cutter-compatible drill units.

The HOUGEN 12160 is suited for structural steel fabrication, pipe fitting, and general metalworking applications where accurate, burr-minimized holes are required in mild steel and steel. It is a standard choice for job sites and shop environments that rely on mag-drill systems requiring a 3/4 inch Weldon shank interface. The bright, uncoated finish makes it easy to inspect the cutting edges for wear during regular maintenance.

Key Features

• 1.875 inch cutter diameter for precise, full-diameter hole cutting
• 1 inch depth of cut handles typical structural steel and plate thicknesses
• High speed steel construction provides good toughness and edge retention in steel
• 3/4 inch Weldon flat shank with 2 flats ensures positive drive and prevents rotation under torque
• Bright/uncoated finish allows easy visual inspection of cutting edges
• Annular cutting action removes only the core, reducing cycle time and heat compared to solid twist drills

Compatibility

Designed for use with magnetic drill presses and drill units that accept a 3/4 inch Weldon flat shank. Suitable for cutting mild steel and steel. Verify that your drill unit is rated for the cutter diameter before use.

Installation Notes

Installation and use of annular cutters should be performed by qualified machinists, fabricators, or trade professionals familiar with mag-drill operation. Ensure the drill unit is fully secured to the workpiece and powered down before seating or removing the cutter from the arbor. Use a pilot pin and cutting fluid appropriate for steel to improve hole quality and extend cutter life. Follow all applicable safety standards for metalworking and rotating cutting tools.
