Hougen 12325 Annular Cutter 0.9843 in Hss Weldon Shank

Product Description

The HOUGEN 12325 is a high speed steel annular cutter designed for clean, full-diameter hole cutting in mild steel and general steel fabrication. With a cutter diameter of 0.9843 inches and a cutting depth of 25 millimeters (approximately 0.984 inches), this tool removes only a small core of material rather than a full slug, reducing heat buildup and extending tool life. The Weldon flat shank with two flats and a 3/4-inch shank diameter locks securely into compatible magnetic drill presses and annular cutter chucks. The bright, uncoated finish is standard for high speed steel cutters used in ferrous metal applications.

This cutter is suited for structural steel work, metal fabrication shops, ironworking, and maintenance trades where precise, burr-free holes are required in mild steel plate, tube, or structural sections. It is sized for use with magnetic base drills and drill press setups that accept a 3/4-inch Weldon shank. Typical applications include connection plate drilling, pipe support fabrication, and general steel layout work performed by ironworkers, pipefitters, millwrights, and metal fabricators.

Key Features

• 0.9843-inch cutter diameter for accurate, full-diameter hole cutting
• High speed steel construction for durability in mild and general steel applications
• 3/4-inch Weldon flat shank with 2 flats for positive, non-slip chuck engagement
• Bright, uncoated finish — standard HSS configuration for ferrous metal cutting
• Annular cutting geometry removes only the outer core, reducing cutting force and heat

Compatibility

Designed as an OEM-style replacement and standard production annular cutter compatible with magnetic drill presses and cutter holders that accept a 3/4-inch Weldon flat shank. Material application is rated for mild steel and general steel stock.

Installation Notes

Installation and use should be performed by qualified metalworking tradespeople familiar with magnetic drill press operation. Ensure the magnetic base is fully engaged and the workpiece is clean and flat before energizing the drill. Secure the cutter shank fully into the Weldon chuck and confirm the flat-to-set-screw alignment before operation. Always use the recommended cutting fluid or lubricant for high speed steel cutters to prevent premature edge wear and reduce heat.
