Milwaukee 49-59-1187 Hss Annular Cutter 1-3/16 in

Product Description

The MILWAUKEE 49-59-1187 is a high speed steel (HSS) annular cutter engineered for cutting clean, precise holes in sheet metal and mild steel plate. Its thin-wall construction paired with an advanced tooth geometry allows the cutter to cut, clean, and clear material simultaneously during the drilling cycle. The result is faster hole completion and reduced burring compared to standard twist-drill methods. The cutter measures 1-3/16 inches in diameter and features a 3/4-inch Weldon shank, making it compatible with most small magnetic drill presses and larger units when paired with the appropriate arbor. Weighing 0.27 pounds, it is suited for portable magnetic drill applications in fabrication and structural work.

This annular cutter is designed for mild steel applications including sheet metal work, structural steel fabrication, and on-site drilling with magnetic drill presses. The thin-wall design displaces less material than a conventional hole saw or twist bit for the same finished hole diameter, which reduces heat buildup and extends cutting edge life. Trade professionals in ironworking, mechanical contracting, and steel fabrication will find this cutter useful for repetitive hole production in both shop and field environments. Use with ejector pin part number 49-59-0011 for proper slug ejection during operation.

Key Features

• Advanced tooth geometry cuts, cleans, and clears material simultaneously during drilling
• Thin-wall design removes less material for faster holes and reduced heat
• Produces burr-free holes in sheet metal and mild steel
• 3/4-inch Weldon shank fits most small and large magnetic drill presses
• Compatible ejector pin: 49-59-0011
• Lightweight at 0.27 pounds for portable magnetic drill use

Compatibility

Designed for use with magnetic drill presses equipped with a 3/4-inch Weldon shank arbor. Large magnetic drill presses require the correct arbor adapter for proper fitment.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with magnetic drill press operation and metal cutting safety practices. Ensure the magnetic drill press is firmly seated and the electromagnet is fully engaged on a clean, flat steel surface before beginning the cut. Do not exceed the drill press rated speed for the cutter diameter in use, and always use cutting fluid to extend cutter life and reduce heat. Insert the ejector pin 49-59-0011 before drilling to ensure automatic slug ejection at the end of the cut.
