Hougen 11210 Annular Cutter Hss 0.3937 in 1/4 in Depth

Product Description

The HOUGEN 11210 is a high speed steel annular cutter designed for clean, fast hole cutting in metal without the need to pre-drill a pilot hole. Built from M2 grade high speed steel with a bright, uncoated finish, this cutter measures 0.3937 inches in diameter with a 1/4 inch depth of cut and a 3/8 inch shank diameter. Annular cutters remove only a ring of material rather than a solid core, reducing cutting torque and heat buildup compared to standard twist drills. The result is a more accurate, burr-free hole in less time. This cutter is suited for fabrication shops, ironworkers, and maintenance trades requiring precise holes in structural and plate stock.

The HOUGEN 11210 is designed for use in magnetic drill presses and compatible annular cutter holders fitted with a 3/8 inch shank connection. It cuts through mild steel, stainless steel, and hardened steel, making it appropriate for structural steel fabrication, mechanical and industrial maintenance, and general metalworking applications. The cutter is sold individually and is well suited to both production environments and field service work where a portable mag drill is used.

Installation Notes

Installation and operation of annular cutters should be performed by qualified machinists or metalworking tradespeople familiar with magnetic drill press operation. Ensure the workpiece is secure and the magnetic drill base is fully energized and seated before beginning a cut. Use cutting fluid appropriate for the workpiece material to extend cutter life and reduce heat. Inspect the cutter for chipped or worn teeth before each use and replace if damaged.
