Hougen 11078 Annular Cutter Set 9 Piece Hss

Product Description

The HOUGEN 11078 is a 9-piece high speed steel annular cutter set designed for fast, clean hole-cutting in steel and ferrous materials. The set covers cutter diameters from 7/8 inch through 1-1/2 inches at 1/8-inch increments, with a cutting depth of 1/2 inch per pass. All cutters feature a bright polished finish and mount on a 1/2-inch shank arbor. This set is used by ironworkers, structural fabricators, and maintenance technicians who need a complete range of common hole sizes without sourcing cutters individually.

Annular cutter sets like the 11078 are a standard tool in structural steel fabrication shops, on-site ironwork, and heavy industrial maintenance. The six included cutters span the most frequently punched bolt-hole sizes in structural applications. The set ships complete with the arbor assembly, center punch, and pilot, making it ready to use out of the box with a compatible magnetic drill press.

Key Features

Compatibility

Designed for use with magnetic drill presses and milling machines equipped with a 1/2-inch shank arbor. Verify arbor thread pattern and shank fit with your specific drill press before installation.

Installation Notes

Annular cutter sets are installed and serviced by ironworkers, fabricators, and industrial maintenance technicians. Always power down and de-energize the magnetic drill press before changing cutters or the arbor assembly. Secure the workpiece and confirm the mag drill base has full contact with a flat, clean steel surface before engaging the magnet. Use cutting fluid appropriate for HSS tooling to extend cutter life and maintain cut quality.
