Hougen 12434 Annular Cutter 1.3386 in Hss Weldon Shank

Product Description

The HOUGEN 12434 is a high speed steel annular cutter designed for drilling clean, full-diameter holes through steel and mild steel without a pilot hole through the entire cut depth. The cutter measures 1.3386 inches in diameter with a 50 mm (approximately 1.969 inches) cutting depth and seats into a 3/4-inch Weldon flat shank, which provides positive rotational drive and prevents slippage under load. With two flats on the shank and a bright, uncoated finish, this cutter is suited for use in magnetic drill presses and compatible rotary broaching setups where precision hole quality and tool repeatability are critical.

This annular cutter is built for structural steel fabrication, ironwork, and general metalworking applications where drilling through mild steel or steel plate is required. It is typically used in magnetic drill press operations on job sites or in fabrication shops. The Weldon flat connection system is the industry standard for mag drill arbors, allowing quick tool changes and secure chuck engagement. Licensed tradespeople in structural steel, HVAC ductwork, and electrical conduit work commonly reach for this cutter size when punching mounting or pass-through holes in steel members.

Key Features

• 1.3386-inch cutter diameter produces a consistent, clean hole without a center drill pilot through the full depth
• High speed steel construction provides durability and edge retention when cutting mild steel and steel plate
• 50 mm cutting depth accommodates thicker steel stock in a single pass
• 3/4-inch Weldon flat shank with 2 flats ensures positive drive engagement and compatibility with standard mag drill arbors
• Bright, uncoated finish allows easy visual inspection of cutting edge condition
• Rated for mild steel and steel material applications

Compatibility

Designed for use with magnetic drill presses and rotary broaching units that accept a 3/4-inch Weldon flat shank arbor. Suitable for cutting mild steel and steel per manufacturer material application data.

Installation Notes

Installation and operation should be performed by qualified metalworking tradespeople familiar with magnetic drill press safety procedures. Secure the mag drill base firmly to the workpiece before beginning any cut, and ensure the arbor is fully engaged with both Weldon flats before applying power. Always use cutting fluid appropriate for steel to extend tool life and reduce heat buildup. Inspect the cutting edge for damage before each use and remove the cutter from service if chipping or deformation is observed.
