Milwaukee 49-57-1937 Annular Cutter 1 15/16 in Carbide

Product Description

The MILWAUKEE 49-57-1937 is a threaded Steel Hawg annular cutter designed for cutting clean, accurate holes in steel, stainless steel, cast iron, and aluminum. The cutter uses carbide teeth arranged in an alternating cutting pattern that removes material up to three times faster than a standard twist drill bit. Maximum hole depth is 2 inches. A spring-loaded, self-ejecting pilot pin serves a dual purpose: it centers the cutter at the start of the cut and automatically ejects the slug when the cut is complete. The M18 x 1.5 threaded shank connects to compatible arbors for use with electromagnetic drill presses. This tool is installed by metalworkers, ironworkers, electricians, and mechanical contractors working on structural steel and plate.

The 49-57-1937 is suited for on-site and shop work where precise, burr-minimized holes are required in ferrous and non-ferrous metals. It is commonly used in structural steel fabrication, electrical conduit knockout work, and mechanical equipment installation. Compatible arbors allow use with Milwaukee magnetic drill presses, including the 4262-1 mag drill press using arbor 49-57-0030, and the 4292-1 mag drill press using arbor 49-57-0010. The cutter also accepts a No. 3 Morse taper arbor assembly 49-57-0010. Cutting diameter is 1 15/16 inches with a metric M18 x 1.5 threaded shank.

Key Features

• Alternating tooth geometry cuts up to 3 times faster than twist drill bits in steel and hard metals
• Carbide teeth resist abrasion and extend cutter service life while producing a cleaner hole edge
• Spring-loaded self-ejecting pilot pin centers the cutter and ejects the slug automatically after each cut
• M18 x 1.5 threaded shank fits most electromagnetic drill press arbors
• Rated for up to 2 inch hole depth in steel, stainless steel, cast iron, and aluminum

Compatibility

Compatible with Milwaukee 4262-1 magnetic drill press using arbor 49-57-0030, and Milwaukee 4292-1 magnetic drill press using arbor 49-57-0010. Also compatible with No. 3 Morse taper arbor assembly 49-57-0010. Fits most electromagnetic drill presses that accept M18 x 1.5 threaded annular cutters.

Installation Notes

Annular cutters are installed and operated by qualified metalworkers or tradespeople familiar with electromagnetic drill press operation. Before mounting or changing the cutter, ensure the mag drill is fully powered down and the magnetic base is disengaged. Secure the workpiece and verify arbor thread engagement before beginning the cut. Follow the drill press manufacturer's guidance on cutting fluid use to extend cutter life and reduce heat buildup.
