Hougen 12439 Annular Cutter 1.5354 in Hss Weldon Shank

Product Description

The HOUGEN 12439 is a high speed steel annular cutter designed for drilling clean, full-diameter holes in mild steel and steel stock. It features a 1.5354-inch cutting diameter and a 3/4-inch Weldon flat shank with two flats for secure chuck engagement. Annular cutters remove only a ring of material rather than the full core, reducing cutting force, heat buildup, and operator fatigue compared to twist drills. This cutter is sized for use in magnetic drill presses and compatible annular cutter chucks. The bright, uncoated finish is standard for HSS tooling used in general fabrication and structural steel work.

This cutter is suited for professional metalworking applications including structural steel fabrication, ironwork, and field drilling operations. It is commonly used by ironworkers, pipefitters, electricians, and general contractors who need accurate, burr-free holes in mild steel plate, angle iron, tube, and similar stock. The 50-millimeter cutting depth accommodates material thicknesses up to approximately 1.97 inches, making it practical for a wide range of plate and structural applications.

Key Features

• 1.5354-inch cutting diameter removes only the material ring, reducing required power and cutting time
• High speed steel construction provides durability in mild steel and general steel applications
• 3/4-inch Weldon flat shank with two flats for positive, slip-resistant chuck retention
• 50-millimeter cutting depth handles stock up to approximately 1.97 inches thick
• Bright, uncoated finish suitable for standard HSS annular cutter applications
• Compatible with magnetic drill presses and Weldon-chuck arbors

Compatibility

Designed for use with magnetic drill presses and annular cutter arbors accepting a 3/4-inch Weldon flat shank. Suitable for cutting mild steel and steel as specified by the manufacturer.

Installation Notes

Installation and operation should be performed by qualified tradespeople familiar with magnetic drill press equipment and metal cutting procedures. Ensure the drill press is fully secured to the workpiece before beginning the cut, and confirm the cutter is firmly seated and locked in the Weldon chuck. Always use the appropriate cutting fluid or lubricant recommended for HSS tooling in steel to extend cutter life and maintain cut quality. Wear appropriate PPE, including eye protection and gloves, when operating rotary cutting equipment.
