Hougen 4-18240 Annular Cutter 1-1/4 in Carbide Tipped

Product Description

The HOUGEN 4-18240 is a carbide-tipped annular cutter designed for cutting clean, precise holes in metal workpieces without removing the full core of material. At 1-1/4 inches in diameter with a 4-inch depth of cut, this cutter handles deep-penetration applications that standard twist drills cannot reach efficiently. The 3/4-inch shank diameter with two flats provides positive drive engagement and prevents slippage in compatible magnetic drill press chucks. An oxide straw finish helps reduce friction and aids in chip evacuation during cutting. Licensed electricians, ironworkers, pipefitters, and structural steel fabricators rely on annular cutters like this one for clean hole production in ferrous and non-ferrous metal.

The HOUGEN 4-18240 is suited for use in portable magnetic drill presses and stationary drill press setups where deep-hole cutting in structural steel, mild steel, stainless steel, and aluminum is required. The 4-inch depth of cut makes it appropriate for thick structural members, I-beams, tube steel, and plate stock where a shorter cutter would bottom out before completing the hole. It is commonly used on job sites and in fabrication shops requiring repeatable hole sizing without secondary reaming.

Compatibility

Designed for use with magnetic drill presses and drill press setups accepting a 3/4-inch flatted shank. Compatible material applications listed by the manufacturer include aluminum, mild steel, stainless steel, and steel.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with magnetic drill press operation and metal cutting safety practices. Secure the magnetic drill base firmly to the workpiece before beginning any cut, and verify the cutter is fully seated and locked in the chuck via the flat drive engagement. Use cutting oil or a suitable metalworking lubricant to extend cutter life and manage heat, especially when cutting stainless steel. Disconnect power to the drill before changing cutters or inspecting the shank.
