Hougen 18256 Annular Cutter 1-3/4 in Carbide Tipped

Product Description

The HOUGEN 18256 is a carbide-tipped annular cutter designed for fast, clean through-hole cutting in metal. It produces a full-diameter core plug rather than reducing the entire cut area to chips, which reduces cutting force and extends tool life compared to twist drills. The 18256 features a 1-3/4 inch cutter diameter with a 2 inch depth of cut, and a 3/4 inch shank diameter with 2 flats for positive engagement in compatible magnetic drill press chucks. The oxide straw finish provides baseline corrosion resistance during storage and use. This cutter is suited for licensed metalworkers, ironworkers, pipefitters, and steel fabricators working with structural or sheet metal.

The HOUGEN 18256 is intended for use in magnetic drill presses and annular cutter-compatible drill press units. It is engineered for cutting aluminum, mild steel, stainless steel, and general steel stock. Typical applications include structural steel fabrication, pipe fitting, HVAC ductwork framing, and on-site ironwork where a portable magnetic drill is used to produce clean, burr-minimal holes without pilot bits when a pilot pin is used.

Key Features

• 1-3/4 inch cutter diameter for full-size through-hole cutting
• 2 inch depth of cut accommodates standard structural steel thicknesses
• Carbide-tipped construction for extended tool life across hard and abrasive materials
• 3/4 inch shank with 2 flats provides secure, non-slip chuck engagement
• Oxide straw finish for corrosion resistance during storage
• Compatible material applications include aluminum, mild steel, stainless steel, and steel

Compatibility

Designed for use with magnetic drill presses and annular cutter-compatible drill press units accepting a 3/4 inch flatted shank. Confirmed material applications include aluminum, mild steel, stainless steel, and steel.

Installation Notes

Installation and operation should be performed by qualified metalworkers or tradespeople familiar with magnetic drill press equipment. Ensure the magnetic drill base is fully energized and seated on a clean, flat steel surface before beginning the cut. A cutting fluid or lubricant appropriate for the workpiece material should be applied throughout the cut to prevent overheating the carbide tips. Never force the cutter or operate without the magnetic base fully engaged on the workpiece.
