Milwaukee 49-59-4225 Annular Cutter 2-1/4 in Carbide Tipped

Product Description

The MILWAUKEE 49-59-4225 is a tungsten carbide tipped annular cutter designed for fast, clean hole-cutting in hard metal materials. Built with an advanced tooth geometry, the cutter simultaneously cuts, cleans, and clears chips during drilling, reducing heat buildup and extending tool life. The thin-wall design displaces less material than standard twist drills for the same hole diameter, resulting in faster cycle times and burr-free holes. The cutter measures 3.65 inches in cutting length and features a 3/4-inch Weldon shank. Licensed electricians, ironworkers, pipefitters, and fabricators working with structural steel, stainless steel, and cast iron rely on this tool for production-grade hole-making.

This annular cutter is suited for use in heavy fabrication, structural steel erection, pipe fitting, and maintenance applications where clean, precise holes in hard metals are required. It performs in both residential and commercial/industrial settings when paired with a compatible magnetic drill press. The 2-1/4-inch cutting diameter makes it appropriate for conduit knockouts, pipe pass-throughs, and structural connection holes. It is rated for use in hard metal applications including stainless steel and cast iron where standard HSS cutters struggle to maintain edge life.

Key Features

• Advanced tooth geometry cuts, cleans, and clears chips simultaneously during drilling
• Thin-wall design removes less material per hole, increasing speed and reducing wear on the drill press
• Tungsten carbide tipped cutting edges maintain sharpness in stainless steel and cast iron
• 3/4-inch Weldon shank fits most small and large magnetic drill presses with the appropriate arbor
• Produces burr-free holes without secondary deburring in most applications
• Compatible pilot pin: 49-59-0014

Compatibility

Designed for use with magnetic drill presses accepting a 3/4-inch Weldon shank. Large magnetic drill presses require the correct arbor adapter. Recommended pilot pin is MILWAUKEE 49-59-0014.

Installation Notes

Installation and operation should be performed by qualified tradespeople familiar with magnetic drill press equipment and metal cutting procedures. Secure the magnetic drill press fully to the workpiece before drilling and verify the base magnet holds rated force before engaging the cutter. Always de-energize or lock out any adjacent electrical circuits and relieve system pressure in pipe or vessel applications before cutting. Cutting fluid or oil should be applied consistently during the cut to manage heat and extend cutter life.
