Hougen 3-12256 Annular Cutter 1-3/4 in Hss Weldon

Product Description

The HOUGEN 3-12256 is a high speed steel annular cutter designed for clean, fast through-hole cutting in ferrous materials. With a 1-3/4 inch cutting diameter and a 3 inch depth of cut, this cutter handles deep holes in structural steel, plate, and similar mild steel stock without the material waste and heat buildup associated with twist drills. The Weldon flat shank with two flats provides a positive drive connection and resists slippage under load. The bright, uncoated finish is standard for high speed steel annular cutters used in general fabrication work. Installed by ironworkers, pipefitters, millwrights, and structural fabricators, this cutter fits magnetic drill presses and compatible drill attachments with a 3/4 inch Weldon-style chuck.

The HOUGEN 3-12256 is suited for use in structural steel fabrication, pipe fitting, and general metalworking applications where full-diameter holes are required through mild steel and steel plate. The 3 inch depth of cut makes it practical for heavy plate or stacked material. It is commonly used with portable magnetic drill presses on job sites and in fabrication shops. Material applications listed by the manufacturer include mild steel and steel stock.

Installation Notes

Installation and use of annular cutters should be performed by qualified tradespeople familiar with magnetic drill press operation and metalworking safety practices. Secure the cutter fully in the chuck and verify the Weldon flat seating before operation. Always use cutting fluid appropriate for high speed steel cutters to extend tool life and reduce heat buildup. Ensure the magnetic drill base is fully energized and the work surface is clean and flat before drilling.
