Hougen 11212 Annular Cutter 0.4724 in Hss

Product Description

The HOUGEN 11212 is a high speed steel annular cutter designed for drilling clean, full-diameter holes in metal stock. Built from M2 grade high speed steel with a bright, uncoated finish, this cutter removes only a core slug rather than reducing the entire bore to chips, which reduces heat buildup and extends tool life compared to twist drills. With a cutting diameter of 0.4724 inches (12 millimeters) and a 1/4 inch depth of cut, this is a short-depth cutter suited for sheet metal, structural shapes, and plate work where precision hole size matters. It mounts via a 3/8 inch shank diameter for use in compatible magnetic drill presses and annular cutter holders.

This cutter is used in metal fabrication, structural steel work, and mechanical trades wherever accurate, burr-minimal holes are required in mild steel, stainless steel, or hardened steel. The 12 millimeter diameter is a common sizing for bolt clearance holes, conduit knockouts, and tubing fitment applications in both shop and field environments. Licensed tradespeople including ironworkers, pipefitters, electricians, and millwrights routinely use annular cutters of this size for production and maintenance drilling tasks.

Key Features

• M2 high speed steel construction for durability across mild steel, stainless steel, and hardened steel
• 0.4724 inch (12 millimeter) cutting diameter for precise hole sizing
• 1/4 inch depth of cut suited for sheet and light plate applications
• 3/8 inch shank diameter fits standard annular cutter arbors and magnetic drill holders
• Bright, uncoated finish allows visual inspection of cutting edge condition
• Annular cutting geometry removes only a core slug, reducing cutting force and heat

Compatibility

Designed for use in magnetic drill presses and drill press arbors accepting a 3/8 inch shank annular cutter. Rated for cutting mild steel, stainless steel, and hardened steel.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with metal cutting equipment and safe drilling practices. Ensure the magnetic drill base is fully energized and seated on a clean, flat surface before beginning a cut. Always use cutting fluid or lubricant appropriate for the workpiece material to extend cutter life and improve hole quality. Disconnect the drill from power before changing cutters or inspecting the cutting edge.
