Milwaukee 49-57-0939 Steel Hawg Annular Cutter 15/16 in

Product Description

The MILWAUKEE 49-57-0939 is a quick change tang drive annular cutter designed for high-speed hole cutting in metal. Built with carbide teeth arranged in an alternating cutting pattern, this cutter delivers up to 3 times faster cutting compared to standard twist bits. It cuts holes up to 1 inch deep in steel, stainless steel, cast iron, and aluminum without requiring pre-punching or a pilot hole. The resulting bore has a ream-like finish. Licensed HVAC, mechanical, and electrical contractors working with structural steel, angle iron, or sheet metal will find this cutter a reliable production tool.

The 49-57-0939 is suited for use with electromagnetic and magnetic drill presses in both shop and field environments. It is compatible with arbor 49-57-0012 or 49-57-0013 when used on Milwaukee 4292-1 or 4297-1 magnetic drill presses, and with arbor 49-57-0032 on the Milwaukee 4262-1 mag press. The quick change tang drive allows rapid cutter swaps without tools, reducing downtime between cuts on production runs or rough-in work.
