Milwaukee 49-57-0875 Steel Hawg Annular Cutter 7/8 in

Product Description

The MILWAUKEE 49-57-0875 is a threaded Steel Hawg annular cutter designed for fast, accurate hole cutting in metal. It features carbide teeth arranged in an alternating cutting pattern that drives through steel, stainless steel, cast iron, and aluminum at up to three times the speed of a comparable twist drill bit. The cutter handles hole depths up to 2 inches at a 7/8-inch diameter. A spring-loaded, self-ejecting pilot pin serves as both a centering guide and a plug ejector, reducing cycle time and improving cut accuracy. Licensed HVAC, electrical, plumbing, and mechanical contractors rely on annular cutters like this when field-drilling structural steel, panel knockouts, or pipe penetrations.

This cutter is sized for trade professionals who work with electromagnetic or magnetic drill presses in fabrication shops, job sites, or panel rooms. The 7/8-inch diameter is a common size for conduit knockouts and mechanical penetrations in steel plate or structural members. The carbide tooth construction extends service life on abrasive materials including stainless steel and cast iron, reducing the need for frequent cutter changes during production runs. Compatible arbors allow use with Milwaukee magnetic drill press models in the field or at the bench.

Key Features

• Alternating tooth geometry accelerates cutting speed through steel and ferrous metals
• Carbide teeth resist abrasion and produce a cleaner hole finish compared to high-speed steel cutters
• Spring-loaded self-ejecting pilot pin centers the cut and clears the plug without extra steps
• Cuts up to 2 inches deep at 7/8-inch diameter in a single pass
• M18 x 1.5 metric thread shank for secure arbor engagement
• Compatible with No. 3 Morse taper arbor assembly 49-57-0010 and arbor 49-57-0030

Compatibility

Designed for use with Milwaukee arbor 49-57-0030 on the Milwaukee 4262-1 magnetic drill press, and with arbor 49-57-0010 on the Milwaukee 4292-1 mag press. Also compatible with No. 3 Morse taper arbor assembly 49-57-0010. Works with most electromagnetic drill presses accepting a threaded M18 x 1.5 shank.

Installation Notes

Installation is performed by electricians, pipefitters, ironworkers, and mechanical contractors using a magnetic drill press. Secure the drill press to the workpiece with the electromagnet before engaging the cutter, and verify the pilot pin is seated before starting the cut. Disengage power and release the electromagnet before changing cutters or removing the plug. Follow applicable OSHA and NFPA 70E electrical safety guidelines when working near energized equipment.
