Milwaukee 49-57-1375 Annular Cutter 1-3/8 in Threaded Steel Hawg

Product Description

The MILWAUKEE 49-57-1375 is a threaded Steel Hawg annular cutter designed for fast, clean hole-cutting in steel, stainless steel, cast iron, and aluminum. The cutter features carbide teeth arranged in an alternating cutting pattern that removes material significantly faster than standard twist drill bits. It supports hole depths up to 2 inches and cuts a 1-3/8 inch diameter hole. A spring-loaded, self-ejecting pin serves a dual purpose: it acts as a centering pin during setup and ejects the slug automatically after the cut, reducing cycle time. The shank uses a metric M18 x 1.5 thread and is compatible with No. 3 Morse taper arbor assemblies.

This cutter is intended for use with electromagnetic and magnetic drill presses in fabrication, structural steel, mechanical, and electrical trade applications. It is well-suited for ironworkers, electricians, and pipefitters who drill through steel plate, tube, or structural members on the job site or in the shop. 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 49-57-0010 arbor also fits a No. 3 Morse taper configuration.

Key Features

• Alternating tooth geometry accelerates cutting speed through steel and ferrous materials
• Carbide teeth resist abrasion and extend cutter service life while producing a cleaner hole edge
• Spring-loaded self-ejecting pin doubles as a centering pin for accurate hole placement and fast slug removal
• M18 x 1.5 metric threaded shank for quick-change compatibility with supported arbors
• Cuts holes up to 2 inches deep in steel, stainless steel, cast iron, and aluminum

Compatibility

Compatible with most electromagnetic drill presses. 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.

Installation Notes

Installation and operation of annular cutters on magnetic drill presses should be performed by qualified tradespeople familiar with mag drill setup and safe workholding practices. Always secure the magnetic drill press fully to the workpiece and confirm the base has achieved full magnetic engagement before beginning a cut. Power down and de-energize the drill press before changing cutters or arbors. Wear appropriate eye and face protection when cutting ferrous materials.
