Hougen 11075 Hss Annular Cutter Set 5/16-3/4 in 10 Pc

Product Description

The HOUGEN 11075 is a 10-piece high speed steel annular cutter set covering cutter diameters from 5/16 inch through 3/4 inch, with a 1/4 inch cutting depth per pass. The set includes seven annular cutters in a bright polished finish, a 3/8 inch arbor assembly, a center punch, and a pilot. High speed steel construction provides durability across repeated cuts in mild steel and similar ferrous materials. This set is designed for magnetic drill press use and is installed by electricians, pipefitters, ironworkers, and mechanical contractors who need precise, clean-edged holes without the material waste of twist drilling.

The 11075 set is suited for light-duty to medium-duty metal fabrication, electrical enclosure work, structural steel layout, and general mechanical trade applications. The range of cutter diameters — 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, and 3/4 inch — covers the most common hole sizes encountered in panel work, conduit entry, and steel plate fabrication. The included arbor assembly and pilot simplify setup and reduce runout when switching between cutter sizes on the same arbor.

Key Features

• Seven annular cutters ranging from 5/16 inch to 3/4 inch diameter in a single set
• High speed steel construction for durability in ferrous metal cutting applications
• Bright polished finish reduces friction and aids chip evacuation during cuts
• 1/4 inch cutting depth per pass suits standard plate and sheet stock
• 3/8 inch shank diameter compatible with standard magnetic drill arbor assemblies
• Includes center punch and pilot for accurate hole placement and reduced walkout

Compatibility

Designed for use with magnetic drill presses accepting a 3/8 inch shank arbor assembly. The included arbor assembly is compatible with the seven cutters in this set.

Installation Notes

Annular cutter sets are typically installed and operated by trade professionals using magnetic drill presses on ferrous metal surfaces. Secure the workpiece and verify magnetic base engagement before beginning any cut. Apply cutting fluid to extend cutter life and improve chip evacuation. Inspect the pilot and center punch for wear before each use and replace as needed to maintain hole accuracy.
