Hougen 4-18244 Annular Cutter 1-3/8 in Carbide Tipped

Product Description

The HOUGEN 4-18244 is a carbide-tipped annular cutter designed for fast, clean through-hole cutting in metal fabrication and structural steel work. With a cutting diameter of 1-3/8 inches and a depth of cut reaching 4 inches, this cutter handles thick stock that standard twist drills cannot efficiently penetrate. The 3/4-inch shank diameter with two flats locks securely into compatible magnetic drill press arbors, keeping the cutter stable under load. The oxide straw finish provides a degree of surface protection. Weighing 0.5 pounds, it is light enough for extended overhead or positional work. Licensed HVAC technicians, ironworkers, pipefitters, and fabricators rely on this type of cutter for fast, burr-minimal hole production.

The HOUGEN 4-18244 is suited for drilling through aluminum, mild steel, stainless steel, and general steel plate or structural members. It is used in commercial and industrial fabrication shops, on-site structural steel erection, and mechanical room installations where conduit, pipe, or duct penetrations require precise, large-diameter holes. The 4-inch depth of cut makes it practical for deep sections, heavy angles, and stacked material applications. It fits magnetic drill presses and drill press arbors that accept 3/4-inch flatted shanks.

Key Features

• 1-3/8 inch cutting diameter for consistent, precise hole sizing
• 4-inch depth of cut handles thick structural sections and deep stock
• Carbide-tipped construction for extended tool life on hard materials including stainless steel
• 3/4-inch shank with 2 flats for positive engagement in magnetic drill arbors
• Oxide straw finish for added surface protection
• Lightweight at 0.5 pounds for reduced operator fatigue in positional drilling

Compatibility

Compatible with magnetic drill presses and arbors that accept a 3/4-inch diameter flatted shank. Rated for use in aluminum, mild steel, stainless steel, and general steel applications.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with metal drilling operations and associated safety practices. Always secure the magnetic drill press base fully to the workpiece before beginning the cut, and confirm the arbor is tight and the pilot pin is properly seated. Use appropriate cutting fluid or lubricant for the material being drilled, particularly when working with stainless steel, to prevent heat buildup and premature tip wear. Inspect the carbide tips for chips or wear before each use.
