Milwaukee Tool 49-22-8440 Annular Cutter Set 8 Piece

Product Description

The MILWAUKEE TOOL 49-22-8440 is an 8-piece carbide-tipped annular cutter set covering diameters from 9/16 inches through 1-1/16 inches with a 2-inch cutting depth. Annular cutters remove only the material at the cut perimeter, producing clean, burr-minimal holes in steel plate, structural steel, and fabricated assemblies faster than twist-drill methods. The carbide-tipped cutting edges hold up to repeated use in ferrous metal, reducing the regrind cycle on job sites where cutter life matters. This set is suited to ironworkers, millwrights, pipefitters, and fabricators who operate magnetic drill presses or annular cutter-compatible drill press setups.

The 49-22-8440 set covers the most common hole-size range encountered in structural steel work, pipe support fabrication, and mechanical room steel framing. The eight included cutter diameters are 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, and 1-1/16 inches. This range addresses standard bolt-clearance holes for 1/2-inch through 1-inch fasteners as well as conduit knockouts and pipe-hanger anchor holes that fall within that diameter window. Each cutter delivers a 2-inch cutting depth, accommodating typical structural steel flange and web thicknesses.

Key Features

• 8 cutters in one set spanning 9/16 to 1-1/16 inches diameter
• Carbide-tipped edges for extended cutting life in ferrous metal
• 2-inch cutting depth handles standard structural steel sections
• Annular cutting geometry removes less material than twist-drill bits, reducing heat and cycle time
• Covers eight common bolt-clearance and anchor-hole diameters in a single kit

Compatibility

Designed for use with magnetic drill presses and annular-cutter-compatible drill press chucks that accept the shank style of this set. Verify shank diameter and arbor compatibility with your specific drill press or mag drill before installation.

Installation Notes

Annular cutter sets are installed and changed by qualified tradespeople including ironworkers, millwrights, and pipefitters using the appropriate arbor and chuck for the drill platform in use. Always power down and lock out the drill press or magnetic drill before changing cutters. Use cutting fluid on the workpiece to reduce heat buildup and extend cutter life. Secure the workpiece and confirm the magnetic drill has full contact and proper holding force on the work surface before starting a cut.
