Milwaukee 49-57-4250 Steel Hawg Annular Cutter 4-1/4 in

Product Description

The MILWAUKEE 49-57-4250 is a threaded Steel Hawg annular cutter designed for fast, clean hole cutting in ferrous and non-ferrous metals. It features carbide teeth arranged in an alternating cutting pattern that allows it to cut up to three times faster than standard twist drill bits. The cutter produces holes up to 2 inches deep in steel, stainless steel, cast iron, and aluminum. A spring-loaded, self-ejecting pilot pin serves as both a centering guide and a plug ejector, improving cut accuracy and reducing cycle time. This cutter is built for use with electromagnetic drill presses and accepts an M18 x 1.5 metric threaded shank connection.

This annular cutter is suited for metal fabrication, structural steel work, mechanical contracting, and electrical installation tasks where large-diameter holes must be cut through plate or structural steel. It is compatible with most electromagnetic drill presses. Typical users include ironworkers, pipefitters, electricians, and millwrights who need repeatable, burr-minimized holes without the step-drilling process required by twist bits. The 4-1/4 inch cutting diameter makes it appropriate for larger conduit knockouts, flange bolt patterns, or structural penetrations.

Compatibility

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

Installation Notes

Installation should be performed by a qualified tradesperson familiar with magnetic drill press operation. Secure the electromagnetic drill press firmly to a clean, flat steel surface before energizing the magnet and beginning the cut. Disengage and de-energize the drill press before changing cutters or removing the pilot pin. Use appropriate cutting fluid on the cutter to reduce heat buildup and extend tooth life during prolonged cuts in harder materials.
