Hougen 12318 Annular Cutter 0.7087 in Hss Weldon Shank

Product Description

The HOUGEN 12318 is a high speed steel annular cutter designed for cutting clean, precise holes in mild steel and steel plate. With a cutter diameter of 0.7087 inches (18 millimeters) and a cutting depth of 25 millimeters (approximately 0.984 inches), it delivers full-perimeter cutting action that reduces required torque and produces less waste than a standard twist drill. The shank is a 3/4-inch Weldon Flat design with 2 flats, providing a secure, slip-resistant connection to compatible magnetic drill presses and annular cutter holders. The bright, uncoated finish indicates no additional surface treatment, making it straightforward to inspect for wear.

This cutter is suited for metalworking applications in structural steel fabrication, ironwork, and general metal construction. It is commonly used by ironworkers, pipefitters, and maintenance mechanics who require accurate, burr-minimized holes without center-drilling. The Weldon Flat shank is a widely accepted standard in magnetic drill press tooling, making this cutter a practical fit for job-site and shop use alike. Material applications include mild steel and structural steel sections.

Key Features

• 0.7087-inch (18 mm) cutter diameter for precise hole sizing in steel
• High speed steel construction provides durability in ferrous metal cutting
• 3/4-inch Weldon Flat shank with 2 flats ensures positive drive and prevents slippage
• 25 mm cutting depth suits standard structural steel thickness ranges
• Bright, uncoated finish allows easy visual inspection of cutting edges
• Annular cutting geometry reduces torque demand compared to solid twist drills

Compatibility

Designed for use with magnetic drill presses and annular cutter holders that accept a 3/4-inch Weldon Flat shank. Intended for cutting mild steel and steel stock.

Installation Notes

Installation and use should be performed by qualified metalworkers or mechanics familiar with magnetic drill press operation. Secure the cutter firmly in the holder before engaging the spindle, and verify the locking set screws engage both Weldon flats. Always use cutting fluid or lubricant to extend tool life and improve hole quality. Ensure the magnetic base has a secure, unobstructed contact surface before beginning the cut.
