Milwaukee 49-57-4000 Annular Cutter 4 Inch Steel Hawg

Product Description

The MILWAUKEE 49-57-4000 is a threaded Steel Hawg annular cutter designed for cutting large-diameter holes in ferrous and non-ferrous metals with a magnetic drill press. It features carbide teeth arranged in an alternating cutting pattern that cuts up to three times faster than a standard twist drill bit. The cutter reaches a maximum hole depth of 2 inches and accepts an M18 x 1.5 metric threaded shank. A spring-loaded, self-ejecting center pin doubles as a centering pin during setup and ejects the slug automatically after the cut, reducing cycle time and improving cut accuracy. Licensed electricians, ironworkers, and pipefitters rely on this cutter for structural steel, stainless steel, cast iron, and aluminum.

The 49-57-4000 is intended for use with electromagnetic and magnetic drill presses in industrial and commercial settings. It is compatible with 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. It also accepts a No. 3 Morse taper arbor assembly 49-57-0010. Typical applications include structural steel fabrication, panel knockout work, conduit entry hole drilling, and any task requiring a clean, burr-reduced large-diameter hole through metal plate or tubing.

Key Features

• Alternating tooth form geometry cuts steel up to 3 times faster than twist drill bits
• Carbide teeth resist abrasion and extend cutter service life while producing a cleaner hole edge
• Spring-loaded self-ejecting pin acts as centering pin and ejects plug automatically after cut completion
• M18 x 1.5 metric threaded shank for secure arbor engagement
• Cuts steel, stainless steel, cast iron, and aluminum up to 2 inches deep
• Compatible with most electromagnetic drill presses via appropriate arbor

Compatibility

Compatible with arbor 49-57-0030 on the Milwaukee 4262-1 magnetic drill press, arbor 49-57-0010 on the Milwaukee 4292-1 mag press, and No. 3 Morse taper arbor assembly 49-57-0010. Works with most electromagnetic drill presses that accept an M18 x 1.5 threaded cutter.

Installation Notes

Installation and operation should be performed by qualified tradespeople familiar with magnetic drill press safety procedures. Ensure the drill press is firmly secured to the work surface with the magnet fully energized before starting a cut. Power down and de-energize the drill press before changing cutters or arbors. Use appropriate cutting fluid on the cutter teeth to extend tool life and improve cut quality on hard materials.
