Hougen 12020 Annular Cutter 49/64 in Hss 2 in Depth

Product Description

The HOUGEN 12020 is a high speed steel annular cutter designed for drilling clean, precise holes in metal without the need to pre-drill a pilot hole. It cuts a 49/64-inch diameter hole to a maximum depth of 2 inches, removing only a narrow ring of material rather than a solid core. The 3/4-inch shank diameter features two flats for secure seating in compatible magnetic drill press chucks. Made from M2 high speed steel with a bright, uncoated finish, it is suited for repetitive production use as well as single-trade field applications. Licensed trades and fabricators rely on annular cutters like this to reduce cycle time and extend tool life compared to conventional twist drills.

This cutter is intended for use in magnetic drill presses and other machines that accept a 3/4-inch, 2-flat shank. It is rated for cutting aluminum, mild steel, stainless steel, and general steel stock. Typical applications include structural steel fabrication, pipe fitting, HVAC ductwork framing, electrical conduit rough-in, and mechanical contractor work where frequent through-holes are required in plate or tube material.

Installation Notes

Annular cutters are installed by trades professionals including pipefitters, ironworkers, sheet metal workers, and electricians using magnetic drill presses or compatible drill fixtures. Secure the cutter fully into the chuck and verify both flats are engaged before operation. Always use cutting oil to extend tool life and prevent heat buildup, especially when cutting stainless steel. Follow all applicable OSHA machine guarding requirements and secure the workpiece before energizing the drill.
