Hougen 11207 Annular Cutter 0.2756 in Hss

Product Description

The HOUGEN 11207 is a high speed steel annular cutter designed for clean, fast hole cutting in ferrous and non-ferrous metals. With a cutter diameter of 0.2756 inches (7.00 mm) and a cutting depth of 0.25 inches, it removes only the material at the hole perimeter rather than the full core, reducing cutting force and extending tool life. The 0.375-inch shank diameter provides secure chucking in compatible magnetic drills and drill presses. It arrives in a bright, uncoated finish and is manufactured from M2 high speed steel for heat resistance and edge retention under continuous use. Installation and operation are performed by maintenance technicians, fabricators, and ironworkers.

This cutter is suited for drilling precise holes in mild steel, stainless steel, and hardened steel in fabrication shops, structural steel work, and on-site mechanical installations. Its compact 0.2756-inch diameter makes it appropriate for close-tolerance hole work where twist drills would walk or require excessive force. The 0.375-inch shank fits standard annular cutter chucks on magnetic base drills and bench-mounted drill presses commonly used in trade and industrial settings.

Key Features

• M2 high speed steel construction provides heat resistance and edge durability
• 3/8-inch shank diameter for secure seating in standard annular cutter chucks
• Bright, uncoated finish — inspect edge condition easily between uses
• Rated for mild steel, stainless steel, and hardened steel applications

Compatibility

Designed as a direct-fit annular cutter for magnetic base drills and drill press chucks accepting a 3/8-inch shank. Compatible with hardened steel, mild steel, and stainless steel workpieces per manufacturer material application data.

Installation Notes

Annular cutters should be installed and operated by qualified machinists, fabricators, or maintenance technicians familiar with magnetic drill operation. Secure the workpiece fully before drilling and confirm the magnetic base has adequate holding force for the surface. Apply cutting oil to the cutter and workpiece to manage heat buildup and extend cutting edge life. Inspect the cutting edge for chipping or wear before each use and replace when edge integrity is compromised.
