Hougen 18440 Annular Cutter 1.5748 in Carbide Tipped

Product Description

The HOUGEN 18440 is a carbide-tipped annular cutter designed for fast, efficient hole cutting in metal fabrication and structural steel work. With a cutting diameter of 1.5748 inches (40 mm) and a cutting depth of 2 inches, this cutter handles through-holes in thick stock where twist drills lose efficiency. The 3/4-inch shank diameter with two flats locks securely into compatible magnetic drill press arbors, preventing slippage under load. An oxide straw finish provides corrosion resistance during storage and repeated use. Installed by metalworkers, ironworkers, and fabrication shops, the 18440 is suited for production and field drilling applications.

This annular cutter is rated for use in aluminum, mild steel, stainless steel, and general steel stock. It fits magnetic drill presses and drill stands that accept a 3/4-inch two-flat shank. The 2-inch depth of cut makes it appropriate for heavy plate, structural members, and pipe flanges where a standard depth cutter would fall short. Typical applications include structural steel fabrication, HVAC ductwork support framing, electrical unistrut work, and general metal trade fieldwork.

Compatibility

Designed for use in magnetic drill presses and drill stands accepting a 3/4-inch two-flat shank. Compatible material applications include aluminum, mild steel, stainless steel, and steel.

Installation Notes

Installation and use should be performed by qualified metalworkers or trade professionals familiar with magnetic drill press operation. Secure the workpiece firmly and verify the magnetic base is fully engaged on a clean, flat steel surface before drilling. Always use cutting fluid appropriate for the material being drilled to maximize cutter life and chip evacuation. Inspect the cutter for chipped carbide tips before each use and do not operate at speeds exceeding the drill press manufacturer's recommendations for the cutter diameter.
