Milwaukee 49-59-2012 Hss Annular Cutter 2-1/8 in Sheet Metal

Product Description

The MILWAUKEE 49-59-2012 is a high speed steel (HSS) annular cutter designed for fast, clean hole-making in mild steel and sheet metal. Built with a thin-wall construction and advanced tooth geometry, it cuts, clears, and cleans material in a single pass, reducing cycle time and producing burr-free holes. The cutter features a 3/4 inch Weldon shank, making it compatible with most small and large magnetic drill presses when used with the appropriate arbor. At 2-1/8 inches in diameter and approximately 2.4 inches in length, it handles a wide range of structural and sheet metal drilling tasks. Licensed HVAC, plumbing, and electrical contractors as well as ironworkers and pipefitters rely on this cutter for clean, accurate penetrations in steel plate and sheet metal.

This annular cutter is intended for mild steel applications including sheet metal fabrication, structural steel work, and mechanical, electrical, and plumbing rough-in tasks that require precise, large-diameter holes. Its thin-wall design displaces less material than conventional twist drills or hole saws of the same diameter, resulting in less heat buildup and faster drilling. The 3/4 inch Weldon shank interface is standard across most magnetic drill press platforms, making this cutter a practical fit for common job-site magnetic drills. For pilots that require an ejector pin, use Milwaukee pin 49-59-0011.

Key Features

• Advanced tooth geometry cuts, cleans, and clears material simultaneously for faster hole completion
• Thin-wall design removes less material than competing cutters, reducing heat and improving hole speed
• 3/4 inch Weldon shank fits most small and large magnetic drill presses with the appropriate arbor
• Produces burr-free holes in mild steel and sheet metal in a single pass
• Compatible ejector pin: 49-59-0011

Compatibility

Designed for use with magnetic drill presses equipped with a 3/4 inch Weldon shank arbor. Use ejector pin 49-59-0011 with this cutter. Intended for mild steel and sheet metal applications.

Installation Notes

Annular cutters are installed and serviced by trades professionals including ironworkers, pipefitters, electricians, and plumbers working with structural steel or metal framing. Ensure the magnetic drill press is powered off and the base is firmly secured to the workpiece before mounting or removing the cutter. Always use cutting fluid or lubricant appropriate for HSS tooling to extend cutter life and reduce heat buildup. Inspect the Weldon shank and set screw interface for wear before each use.
