Hougen 3-12272 Annular Cutter 2.25 in 3 in Hss

Product Description

The HOUGEN 3-12272 is a high speed steel annular cutter designed for fast, clean-hole cutting in metalworking applications. With a 2.25-inch cutter diameter and a 3-inch depth of cut, this cutter removes only a slug of material rather than a full core, which reduces heat buildup and extends tool life compared to conventional twist drills. Constructed from M2 high speed steel with a bright, uncoated finish, the 3-12272 is suited for production and maintenance environments where consistent hole quality in metal plate and structural steel is required. It is installed by licensed machinists, fabricators, and maintenance mechanics operating magnetic drill presses or similar annular cutter-compatible equipment.

This cutter is used in industrial fabrication, structural steel work, and maintenance applications on materials including aluminum, mild steel, stainless steel, and general steel stock. The 3-inch depth of cut allows it to handle thicker workpieces that standard annular cutters cannot reach in a single pass. The 0.75-inch shank diameter with two flats ensures positive drive engagement and prevents slippage in compatible magnetic drill press chucks.

Key Features

• 2.25-inch cutter diameter for large-diameter hole cutting in one pass
• 3-inch depth of cut handles thick plate and structural sections
• M2 high speed steel construction for durability across multiple material types
• 0.75-inch shank with 2 flats for positive chuck engagement and slip prevention
• Bright, uncoated finish — no coating to chip or delaminate during hard use
• Compatible with aluminum, mild steel, stainless steel, and general steel applications

Compatibility

Designed for use with magnetic drill presses and annular cutter holders accepting a 0.75-inch flatted shank. Suitable for cutting aluminum, mild steel, stainless steel, and general steel workpieces.

Installation Notes

Installation and operation should be performed by qualified machinists or metalworking professionals familiar with magnetic drill press equipment. Secure the workpiece and verify the magnetic base is fully energized and seated on a clean, flat surface before cutting. Use appropriate cutting fluid or coolant to reduce heat and extend cutter life. Inspect the shank and flats for wear before each use and replace if deformation is present.
