Hougen 4-18234 Annular Cutter 1-1/16 in Carbide Tipped

Product Description

The HOUGEN 4-18234 is a carbide-tipped annular cutter designed for fast, clean through-holes in metal plate, structural steel, and fabricated assemblies. With a cutting diameter of 1-1/16 inches and a depth of cut of 4 inches, this cutter handles thick structural sections where standard twist drills lose efficiency or require pilot hole steps. The 3/4-inch shank with two flats locks securely into compatible magnetic drill press chucks, preventing slippage under load. The oxide straw finish provides light corrosion resistance during storage and use. Fabricators, ironworkers, pipefitters, and maintenance welders are the primary installers of this tool.

This annular cutter is suited for production and field drilling applications in light fabrication shops, structural steel erection, and mechanical piping installations. It performs in aluminum, mild steel, stainless steel, and general steel. The 4-inch depth of cut makes it practical for deep-section beams, heavy plate, and stacked material applications where shorter cutters cannot reach through in a single pass. It is sold individually and is appropriate for shops running moderate to high hole-count jobs where carbide longevity justifies the tool cost.

Key Features

• 1-1/16 inch cutting diameter for standard structural and piping hole patterns
• 4 inch depth of cut handles thick plate and deep-section steel in one pass
• Carbide-tipped construction extends tool life on abrasive and hard materials including stainless steel
• 3/4 inch shank with 2 flats provides positive drive engagement in magnetic drill chucks
• Oxide straw finish offers basic corrosion protection during storage and field use
• Compatible material applications include aluminum, mild steel, stainless steel, and general steel

Compatibility

Designed for use with magnetic drill presses and annular cutter holders accepting a 3/4 inch flatted shank. Suitable for drilling aluminum, mild steel, stainless steel, and general steel stock.

Installation Notes

Installation and operation should be performed by qualified machinists, fabricators, or ironworkers familiar with magnetic drill press equipment. Secure the workpiece fully before engaging the magnet base and verify the chuck is locked onto both flats of the shank before starting the cut. Use cutting fluid appropriate for the material being drilled to maximize cutter life and chip evacuation. Inspect the carbide tips for chipping or wear before each use and replace the cutter if tip integrity is compromised.
