Milwaukee 49-59-2144 Hss Annular Cutter 1-7/16 in Sheet Metal

Product Description

The MILWAUKEE 49-59-2144 is a high speed steel (HSS) annular cutter designed for drilling clean, precise holes in sheet metal and mild steel plate. It features a thin-wall construction paired with an advanced tooth geometry that cuts and clears material simultaneously, reducing heat buildup and extending tool life. The cutter measures 1-7/16 inches in diameter and 3.386 inches in length, and it mounts via a 3/4-inch Weldon shank compatible with most small and large magnetic drill presses. Licensed HVAC sheet metal fabricators, pipefitters, electricians, and ironworkers rely on this type of cutter for fast, burr-free hole production on the job site or in the shop.

This annular cutter is intended for use in mild steel applications, including sheet metal fabrication, structural steel work, and general metalworking where clean-edged holes are required. The thin-wall design displaces less material than standard twist drills or competing annular cutters of the same diameter, which translates directly to faster cycle times and reduced motor load on the magnetic drill press. Use ejector pin part number 49-59-0012 for proper slug ejection during operation.

Key Features

• Advanced tooth geometry cuts and cleans the hole simultaneously, reducing burrs and secondary finishing
• Thin-wall construction removes less material per hole compared to solid twist drills, increasing speed and reducing wear
• 3/4-inch Weldon shank fits most small magnetic drill presses and large magnetic drill presses with the appropriate arbor
• Optimized for mild steel and sheet metal applications
• Compatible ejector pin: 49-59-0012

Compatibility

Fits magnetic drill presses equipped with a 3/4-inch Weldon shank arbor. Use with ejector pin 49-59-0012 for slug ejection. Designed for mild steel and sheet metal cutting applications.

Installation Notes

Installation and operation should be performed by a qualified tradesperson familiar with magnetic drill press safety procedures. Secure the magnetic drill press base fully to a clean, flat steel surface before operation and verify the cutter is locked firmly into the Weldon shank arbor. Cutting fluid or lubricant appropriate for HSS tooling in steel is recommended to extend cutter life and maintain hole quality. Never exceed the drill press manufacturer's rated speed range for the cutter diameter in use.
