Hougen 17130 Annular Cutter 15/16 in Cobalt M42

Product Description

The HOUGEN 17130 is a cobalt annular cutter designed for fast, efficient hole cutting in ferrous and hard metals. Built from M42 cobalt high-speed steel, it delivers a 15/16-inch cutting diameter with a 3/4-inch depth of cut. The Rotaloc twist-style bayonet shank provides a secure, quick-change connection to compatible magnetic drill presses. The bright, uncoated finish is standard for cobalt-grade cutters in this class. Licensed electricians, ironworkers, pipefitters, and structural fabricators reach for this cutter when production hole quality and tool longevity matter on tough materials.

The HOUGEN 17130 is suited for stack cutting applications on mild steel, stainless steel, and general steel stock. The 15/16-inch diameter is a common size for structural bolt clearance and conduit knockout work. The 5/8-inch shank diameter fits the Rotaloc twist-style connection found on HOUGEN magnetic drills and compatible third-party mag drill bases. It is appropriate for both shop and field use wherever a mag drill is the primary hole-making tool.

Installation Notes

Installation is performed by qualified tradespeople familiar with magnetic drill press operation. Ensure the mag drill is fully secured to the workpiece and the power source is disconnected before changing cutters. Always use the appropriate cutting fluid for the material being cut to extend tool life and maintain cut quality. Follow the drill manufacturer's recommended RPM range for the cutter diameter to avoid tool damage or workpiece distortion.
