Hougen 12329 Annular Cutter 1.1417 in Hss Weldon Shank

Product Description

The HOUGEN 12329 is a high speed steel annular cutter designed for cutting precise, clean holes in mild steel and general steel workpieces. With a cutter diameter of 1.1417 inches (29 millimeters) and a cutting depth of 25 millimeters, this cutter removes only a core of material rather than reducing the entire hole area to chips, which reduces cutting forces and heat. The 3/4-inch Weldon flat shank with two flats provides a secure, positive drive connection in compatible magnetic drill presses and annular cutter arbors. The bright, uncoated finish is standard for high speed steel annular cutters used in general metalworking and structural fabrication applications.

The HOUGEN 12329 is suited for field and shop use in structural steel fabrication, ironwork, and general metalworking. It is typically used with magnetic drill presses in applications where a standard twist drill would be impractical due to hole size or material thickness. The cutter is appropriate for electricians, ironworkers, pipefitters, and general fabricators cutting bolt holes, conduit openings, and connection points in mild steel plate and structural members.

Key Features

• 1.1417-inch (29 mm) cutter diameter for consistent, accurate hole sizing
• 25 mm cutting depth accommodates typical structural steel thicknesses
• High speed steel construction provides durability in mild steel and general steel cutting
• 3/4-inch Weldon flat shank with two flats for positive, slip-resistant drive engagement
• Bright, uncoated finish — no coating to chip or delaminate during use

Compatibility

Designed for use with magnetic drill presses and annular cutter arbors accepting a 3/4-inch Weldon flat shank. Rated for cutting mild steel and general steel workpieces.

Installation Notes

Installation and use of annular cutters should be performed by qualified tradespeople familiar with magnetic drill press operation. Ensure the magnetic drill base is fully energized and the workpiece is clean and flat before beginning a cut. Always use a pilot pin and cutting fluid appropriate for high speed steel cutters on steel to extend cutter life and improve cut quality. Disconnect power to the drill before changing cutters.
