Hougen 12342 Annular Cutter 1.6535 in Hss Weldon

Product Description

The HOUGEN 12342 is a high speed steel annular cutter designed for clean, fast hole cutting in ferrous metals. Unlike twist drills, annular cutters remove only a core of material, reducing the force and heat required to complete each hole. The 12342 features a 1.6535-inch cutting diameter and a 3/4-inch Weldon flat shank with two flats for positive drive engagement. Cutting depth reaches 25 millimeters (approximately 0.984 inches). This cutter ships uncoated in a bright finish and is suited for use with magnetic drill presses and annular cutter-compatible drill stands. Metalworkers, ironworkers, and fabricators are the primary installers of this tool.

The HOUGEN 12342 is intended for structural fabrication, ironwork, and general metal cutting applications where a full-size through-hole is required in mild steel or steel stock. The Weldon flat shank design provides a secure, non-slip connection in compatible magnetic drill press chucks. Cutting diameter of 1.6535 inches makes this cutter appropriate for applications requiring a 42-millimeter hole. This cutter is sold individually and is used in shop and field settings where magnetic drill presses are standard equipment.

Key Features

• 1.6535-inch (42 mm) cutting diameter for precise, repeatable hole sizing
• High speed steel construction provides durability in mild steel and steel applications
• 3/4-inch Weldon flat shank with two flats for positive drive and minimal slippage
• 25 mm cutting depth accommodates standard structural steel thicknesses
• Bright uncoated finish allows easy visual inspection of cutting edge condition
• Annular cutting geometry reduces heat buildup and cutting force compared to twist drills

Compatibility

Designed for use with magnetic drill presses and drill stands accepting a 3/4-inch Weldon flat shank. Rated for cutting mild steel and steel. Verify chuck compatibility with your specific drill press before installation.

Installation Notes

Installation and use of this cutter should be performed by a qualified metalworker or fabricator familiar with magnetic drill press operation. Ensure the magnetic drill press is fully powered down and the chuck is secured before changing cutters. Always use the recommended cutting fluid for the material being drilled to extend cutter life and maintain cut quality. Follow the drill press manufacturer's RPM guidelines for the selected cutter diameter.
