Milwaukee 49-57-8106 Steel Hawg Annular Cutter 1-1/16 in

Product Description

The MILWAUKEE 49-57-8106 is a one-piece Steel Hawg annular cutter designed for fast, precise hole cutting in ferrous metals. Carbide teeth with an alternating tooth form geometry allow this cutter to drill holes up to 3 times faster than standard twist bits while producing a cleaner cut edge. The milled 3-flat shank fits standard 1/2-inch chucks. At 0.43 pounds and 7.2 inches in total length, it is a compact tool for jobsite or shop use. Licensed HVAC, plumbing, electrical, and mechanical contractors reach for this cutter when they need clean, accurate holes in steel, stainless steel, or cast iron up to 1/2 inch thick.

The 49-57-8106 is Milwaukee's most popular specialty steel drilling accessory in this size class. Its 1-1/16-inch cutting diameter is sized 1/16 inch larger than a standard bolt, making it a go-to choice for electrical and mechanical installers cutting bolt clearance holes in structural steel, panel enclosures, and equipment mounting plates. It is compatible with most electromagnetic drill presses and most 1/2-inch chucks, covering a wide range of existing tool inventory on any crew.
