Hougen 12642 Annular Cutter 1-5/16 in Hss Tin

Product Description

The HOUGEN 12642 is a high speed steel annular cutter designed for fast, clean through-holes in metal plate and structural steel. It cuts a 1-5/16 inch diameter hole to a depth of 1 inch, removing only a thin ring of material rather than a solid slug, which dramatically reduces the force and power required compared to a twist drill. The cutter is manufactured from M2 high speed steel and finished with a titanium nitride (TiN) coating that extends cutting life and reduces heat buildup at the cutting edge. It is installed and removed by licensed machinists, ironworkers, and fabricators working on steel fabrication, structural erection, and maintenance applications.

The HOUGEN 12642 is suited for use in magnetic drill presses and other drill press platforms that accept a 3/4 inch Weldon flat shank. Typical applications include drilling bolt holes, access holes, and fixture holes in mild steel, stainless steel, and general steel stock. The two-flat Weldon shank provides positive drive engagement and prevents slippage under load. This cutter is a practical fit for fabrication shops, field ironwork, and maintenance operations where repeatable hole quality matters.

Key Features

• 1-5/16 inch cutting diameter for standard bolt and access hole sizing
• 1 inch depth of cut accommodates typical plate and structural member thicknesses
• M2 high speed steel construction for durability across mild and stainless steel applications
• Titanium nitride (TiN) coating extends cutting edge life and reduces friction
• 3/4 inch Weldon flat shank with 2 flats for positive drive and slip resistance
• Annular cutting geometry removes a ring rather than a full slug, reducing required torque and power

Compatibility

Designed for use in magnetic drill presses and drill press fixtures accepting a 3/4 inch Weldon flat shank. Rated for cutting mild steel, stainless steel, and general steel materials.

Installation Notes

Installation and operation should be performed by qualified machinists, fabricators, or ironworkers familiar with magnetic drill press operation. Always secure the magnetic drill base fully to a clean, flat steel surface and confirm the arbor is locked before beginning a cut. Use an appropriate cutting fluid or coolant to maintain cutting edge life and manage heat, especially when cutting stainless steel. Inspect the cutter for chipped or worn teeth before each use and remove the pilot pin before mounting if the application does not require it.
