Hougen 17842 Cobalt Annular Cutter 1-5/16 in 1 in Cut

Product Description

The HOUGEN 17842 is a cobalt annular cutter designed for drilling clean, precise holes in steel and other ferrous metals. Built from M42 cobalt high-speed steel, it delivers superior heat and wear resistance compared to standard HSS cutters, making it well-suited for tough materials and repetitive production drilling. The cutter measures 1-5/16 inches in diameter with a 1-inch depth of cut and connects via a 5/8-inch Rotaloc twist-style bayonet shank. It ships with a bright, uncoated finish and weighs 0.26 pounds. Licensed HVAC sheet metal fabricators, pipefitters, ironworkers, and structural steel crews rely on annular cutters like this for efficient, burr-minimizing hole production.

The HOUGEN 17842 is appropriate for use on structural steel, plate, tube, angle iron, and similar ferrous stock in both shop and field environments. The Rotaloc twist-style bayonet connection is compatible with magnetic drill presses and other drive systems that accept the standard 5/8-inch Rotaloc-style shank interface. It is packaged individually and is well-suited for maintenance, fabrication, and construction trades that require consistent hole quality without the pilot-hole step required by conventional twist drills.

Key Features

• M42 cobalt high-speed steel construction for extended tool life in ferrous materials
• 1-5/16 inch cutting diameter for a consistent, full-diameter hole in a single pass
• 1-inch depth of cut accommodates typical structural steel thicknesses
• 5/8-inch Rotaloc twist-style bayonet shank for secure, tool-free mounting on compatible magnetic drills
• Bright, uncoated finish — no coating buildup to affect dimensional tolerance
• No Weldon flat, no flatted shank — clean round shank profile for the Rotaloc drive system

Compatibility

Designed for use with magnetic drill presses and drill stands that accept a 5/8-inch Rotaloc twist-style bayonet shank connection.

Installation Notes

Annular cutters of this type are installed and removed by a licensed or qualified metalworking technician or fabricator using a compatible magnetic drill press. Before mounting or changing the cutter, ensure the drill unit is powered off and the magnetic base is disengaged. Use a cutting fluid or lubricant appropriate for cobalt tooling and the workpiece material to extend tool life and maintain cut quality. Always secure the workpiece and verify the magnetic base has adequate contact area before beginning a cut.
