Milwaukee 49-57-1750 Annular Cutter 1-3/4 in Steel Hawg

Product Description

The MILWAUKEE 49-57-1750 is a threaded Steel Hawg annular cutter designed for fast, clean hole cutting in ferrous and non-ferrous metals. The cutter features carbide teeth arranged in an alternating cutting pattern that drives material removal up to three times faster than standard twist drill bits. It cuts holes up to 2 inches deep in steel, stainless steel, cast iron, and aluminum. The M18 x 1.5 metric threaded shank seats in compatible arbors for electromagnetic drill presses. A spring-loaded, self-ejecting pilot pin functions as both a centering guide and plug ejector. Licensed electricians, ironworkers, pipefitters, and mechanical contractors are the primary users of this cutter.

This annular cutter is built for production hole-making in structural steel, plate stock, and heavy fabrication applications. It is suited for use with electromagnetic mag drill presses in both shop and field settings. Compatible arbors include 49-57-0030 for use with the Milwaukee 4262-1 magnetic drill press and 49-57-0010 for the Milwaukee 4292-1 mag press. The cutter also accepts a No. 3 Morse taper arbor assembly 49-57-0010. The 1-3/4 inch diameter cut is common in pipe penetration, conduit knockout, and structural attachment work.

Key Features

• Alternating tooth form geometry increases cutting speed versus conventional twist drill bits
• Carbide teeth provide abrasion resistance and extended cutter life in hard metals
• Spring-loaded self-ejecting pilot pin centers the cut and ejects the slug automatically
• M18 x 1.5 metric threaded shank for secure arbor engagement
• Cuts up to 2 inches deep in steel, stainless steel, cast iron, and aluminum
• Compatible with most electromagnetic drill presses via appropriate arbor

Compatibility

Designed for use 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. Fits most electromagnetic drill presses that accept an M18 x 1.5 threaded shank or compatible Morse taper arbor.

Installation Notes

Installation and operation of annular cutters on magnetic drill presses should be performed by qualified trade professionals following the drill press manufacturer's instructions. Secure the magnetic base fully to the workpiece before operation and confirm the cutter is seated and locked in the arbor before starting the drill. Always use cutting fluid when drilling stainless steel or thick plate to extend cutter life and manage heat buildup. Wear appropriate PPE including eye protection and gloves when operating rotary cutting tools.
