Milwaukee 49-57-1877 Steel Hawg Annular Cutter 1-7/8 in

Product Description

The MILWAUKEE 49-57-1877 is a quick change tang drive annular cutter designed for fast, clean hole cutting in ferrous and non-ferrous metals. Built with abrasion-resistant carbide teeth and an alternating tooth form geometry, it cuts holes up to 1 inch deep in steel, stainless steel, cast iron, and aluminum. The cutter weighs 0.53 pounds and is sold as an individual unit. It is designed for use with electromagnetic drill presses and delivers a ream-like finish without requiring pre-punching or pilot hole preparation. Licensed trade professionals and experienced metal fabricators install this tool in structural, mechanical, and industrial applications.

This annular cutter is suited for commercial and industrial jobsite use where speed and hole quality are critical. It is compatible with most electromagnetic drill presses and is specifically designed to work with Milwaukee mag drill models when paired with the correct arbor. The quick change tang drive system allows fast tool swaps, reducing downtime between cuts. Applications include steel fabrication, ironwork, HVAC ductwork framing, electrical conduit layout, and general structural steel drilling where round, clean-edged through-holes are required.
