Hougen 11215 Annular Cutter 0.5906 in Hss 1/4 in Depth

Product Description

The HOUGEN 11215 is a high speed steel (HSS) annular cutter designed for fast, clean through-holes in metal without the material waste of a standard twist drill. It cuts only the outer ring of material, producing a precise hole and a solid slug. The cutter measures 0.5906 inches in diameter with a 1/4 inch depth of cut and accepts a 3/8 inch shank. The bright, uncoated finish is standard for M2 HSS tooling. This cutter is installed in magnetic drill presses and is used daily by ironworkers, structural steel fabricators, and millwrights.

This annular cutter is suited for drilling structural steel, mild steel, stainless steel, and hardened steel plate. It fits any magnetic drill press or drill press arbor that accepts a 3/8 inch shank. Typical applications include fabrication shops, steel erection, equipment mounting, and maintenance work where clean, burr-minimal holes are required in metal plate or structural members. The 0.5906 inch (15 mm) diameter is a common size for fastener clearance and bolt-hole work.

Key Features

Compatibility

Designed for use with magnetic drill presses and drill press arbors accepting a 3/8 inch shank. Rated for cutting hardened steel, mild steel, and stainless steel.

Installation Notes

Annular cutters should be installed by machinists or qualified fabricators following standard magnetic drill press procedures. Secure the cutter fully into the arbor and confirm the shank is fully seated before operation. Use cutting fluid or coolant appropriate for HSS tooling to extend cutter life, particularly when drilling stainless or hardened steel. Always clamp or otherwise secure the workpiece before engaging the magnetic base and beginning the cut.
