Hougen 12005 Hss Annular Cutter Set 5/8 to 1-1/8 in 8 Pc

Product Description

The HOUGEN 12005 is an 8-piece high speed steel annular cutter set covering diameters from 5/8 inch through 1-1/8 inch with a 1-inch cutting depth. The set includes five annular cutters, two pilots, and one hex wrench, giving a technician or ironworker the core tooling needed for magnetic drill press work. The bright polished finish reduces friction during the cut and helps with chip ejection. The 3/4-inch shank diameter features two flats for secure, positive engagement in the drill arbor, minimizing slippage under load.

This set is suited for metalworking applications where clean, burr-minimized through-holes are required in structural steel, plate, and similar ferrous stock. The cutter diameter range of 5/8, 3/4, 7/8, 1, and 1-1/8 inches covers the most common hole sizes encountered in steel fabrication, erection, and maintenance work. Annular cutters of this type are typically run on magnetic-base drills and are standard tooling in structural steel, mechanical, and heavy industrial trades.

Key Features

• Five annular cutters spanning 5/8, 3/4, 7/8, 1, and 1-1/8 inch diameters
• High speed steel construction for durability in ferrous metal cutting
• 1-inch cutting depth per pass
• Bright polished finish reduces friction and aids chip clearance
• 3/4-inch shank with two flats for positive arbor lock
• Includes two pilots and one hex wrench for complete out-of-box use

Compatibility

Designed for use with magnetic-base drill presses and arbors accepting a 3/4-inch flatted shank. Confirm your drill arbor accepts a 3/4-inch shank with two flats before installation.

Installation Notes

Annular cutter sets of this type are installed and serviced by machinists, ironworkers, and mechanical contractors using magnetic-base drill presses. Before changing cutters, ensure the magnetic drill is powered off and the magnet is fully de-energized. Insert the pilot through the cutter prior to seating the shank in the arbor, and secure with the provided hex wrench against both flats to prevent rotation under load. Always use cutting fluid rated for high speed steel on ferrous stock to extend tool life and maintain cut quality.
