Hougen 11209 Annular Cutter 0.3543 in Hss 1/4 in Depth

Product Description

The HOUGEN 11209 is a high speed steel annular cutter designed for clean, full-diameter hole cutting in metal. Unlike twist drills, annular cutters remove only a core of material at the perimeter of the hole, reducing cutting force and producing a precise, burr-minimized bore. The 11209 features a 0.3543-inch cutting diameter, a 0.25-inch depth of cut, and a 3/8-inch shank diameter for direct mounting to magnetic drill presses and compatible drill adapters. Finished in a bright, uncoated surface, this cutter is built from M2 high speed steel for durability across a range of ferrous metals.

The HOUGEN 11209 is suited for use in fabrication shops, structural steel work, and on-site metal cutting tasks where a clean through-hole is required. It is appropriate for use in residential and commercial construction, HVAC ductwork framing, electrical panel mounting, and similar applications involving thin to medium gauge steel. Licensed tradespeople including ironworkers, pipefitters, electricians, and HVAC mechanics commonly use annular cutters of this type when drilling with a magnetic drill press or drill press fixture.

Key Features

• 0.3543-inch (9.00 mm) cutting diameter for precise hole sizing
• 0.25-inch depth of cut suitable for sheet metal and light structural stock
• 3/8-inch shank diameter for secure chuck or arbor connection
• M2 high speed steel construction for heat resistance and edge retention
• Bright/uncoated finish — no coating buildup to affect hole tolerance
• Compatible with hardened steel, mild steel, and stainless steel workpieces

Compatibility

Designed for use with magnetic drill presses and drill press fixtures accepting a 3/8-inch shank. Rated for cutting hardened steel, mild steel, and stainless steel.

Installation Notes

Annular cutters of this type are installed by qualified tradespeople using magnetic drill presses or stationary drill press equipment. Secure the workpiece fully before cutting and confirm the magnetic base is properly energized and seated before operation. Use cutting oil or coolant appropriate for the workpiece material to extend cutter life and reduce heat buildup. Always de-energize and secure the drill press before changing or inspecting the cutter.
