Hougen 11166 Annular Cutter 1-3/8 in Hss Bright

Product Description

The HOUGEN 11166 is a high speed steel annular cutter designed for fast, efficient hole-cutting in ferrous metals. Annular cutters remove only a core of material rather than a full slug, which reduces heat buildup, lowers required torque, and extends cutter life compared to twist drills. The 11166 features a 1-3/8 inch cutting diameter and a 1/2 inch depth of cut, with a 1/2 inch shank diameter that fits standard magnetic drill press arbors. The cutter is manufactured from M2 high speed steel with a bright, uncoated finish. It is appropriate for use by machinists, ironworkers, structural steel fabricators, and maintenance mechanics working with steel plate and structural members.

The HOUGEN 11166 is suited for applications involving mild steel, stainless steel, and hardened steel. It is commonly used in structural fabrication shops, field ironworking, manufacturing maintenance, and metal fabrication environments where clean, burr-minimal through-holes are required. The 1/2 inch shank is the industry-standard connection size for magnetic drill presses and drill press arbor adapters. This cutter is a practical choice wherever a precise, flat-bottomed hole is needed and a standard twist drill would produce excessive heat or require pilot drilling.

Key Features

• 1-3/8 inch cutting diameter for clean, accurate holes in metal stock
• 1/2 inch depth of cut suitable for standard plate thicknesses
• M2 high speed steel construction for durability in ferrous metal cutting
• 1/2 inch shank diameter fits standard magnetic drill press arbors
• Bright, uncoated finish — no coating to chip or delaminate during use
• Cuts mild steel, stainless steel, and hardened steel in a single pass

Compatibility

Compatible with magnetic drill presses and drill press arbors accepting a 1/2 inch shank. Rated for use in mild steel, stainless steel, and hardened steel applications.

Installation Notes

Annular cutters are installed by metalworkers and machinists using magnetic drill presses or drill press arbors — secure the cutter firmly in the arbor before operation and confirm the pilot pin is properly seated. Always clamp or magnetically secure the workpiece and ensure the magnetic drill base has full, flat contact with the work surface before engaging the cutter. Use cutting oil or an appropriate metalworking lubricant to reduce heat and extend cutter life. Wear appropriate PPE including eye protection and gloves when operating.
