Milwaukee 49-57-1689 Steel Hawg Annular Cutter 1-11/16 in

Product Description

The MILWAUKEE 49-57-1689 is a quick-change tang drive annular cutter designed for fast, clean hole cutting in steel, stainless steel, cast iron, and aluminum. Built for use with electromagnetic drill presses, this cutter features carbide teeth arranged in an alternating cutting pattern that delivers up to 3 times faster material removal compared to standard twist bits. It cuts holes up to 1 inch deep and produces a ream-like finish without requiring pre-punching or pilot holes. The self-ejecting pin also functions as a centering pin for accurate positioning and faster plug removal. Licensed electricians, ironworkers, pipefitters, and mechanical contractors rely on this cutter for structural and equipment fabrication.

This annular cutter is suited for commercial and industrial applications where clean, accurate holes are needed in ferrous and non-ferrous plate stock, structural steel, and equipment enclosures. It is compatible with most electromagnetic drill presses using a standard tang drive arbor. For Milwaukee magnetic drill presses, use arbor 49-57-0012 or 49-57-0013 with the 4292-1 or 4297-1 mag drill, or arbor 49-57-0032 with the 4262-1 mag drill.

Key Features

• Alternating tooth form geometry removes material up to 3 times faster than conventional drill bits
• Abrasion-resistant carbide teeth extend cutter life and produce a cleaner bore finish
• Cuts up to 1 inch depth in steel, stainless steel, cast iron, and aluminum without pre-punching
• Spring-loaded, self-ejecting pin serves as both a centering pin and plug ejector for faster changeovers
• Quick-change tang drive design reduces changeover time between cuts
• No pilot hole required — reduces setup steps on the job

Compatibility

Compatible with most electromagnetic drill presses using a tang drive arbor. For Milwaukee mag drills, use arbor 49-57-0012 or 49-57-0013 with the 4292-1 or 4297-1, or arbor 49-57-0032 with the 4262-1.

Installation Notes

This cutter is installed and operated by trades professionals including electricians, pipefitters, ironworkers, and mechanical contractors. Before mounting or changing the cutter, ensure the magnetic drill press is powered off and the magnet is fully deactivated. Secure the arbor according to the drill press manufacturer torque guidance. Always clamp or secure the workpiece before engaging the mag drill base to prevent movement during cutting.
