Milwaukee 49-59-2188 Hss Annular Cutter 1-7/8 in Sheet Metal

Product Description

The MILWAUKEE 49-59-2188 is a high speed steel (HSS) annular cutter engineered for fast, clean hole cutting in mild steel and sheet metal applications. Its thin-wall construction removes less material than traditional cutters, reducing the force needed to complete each hole. An advanced tooth geometry cuts and clears chips simultaneously, producing burr-free holes without secondary deburring. The 3/4 inch Weldon shank is compatible with most small and large magnetic drill presses when paired with the appropriate arbor. This cutter is used by ironworkers, pipefitters, and structural steel fabricators who need repeatable, accurate holes in production or field conditions.

The 49-59-2188 is suited for mild steel sheet metal and plate applications where speed and hole quality matter. Its 1-7/8 inch cutting diameter and thin-wall design allow it to produce clean through-holes faster than twist drills of comparable size. It is intended for use with magnetic drill presses and compatible arbors. The cutter requires a pilot pin for proper centering during operation; the recommended pin is 49-59-0012. Typical users include structural fabricators, mechanical contractors, and industrial maintenance technicians working with steel plate or structural members.

Key Features

• Advanced tooth geometry cuts and clears chips while drilling for faster hole completion

• Produces burr-free holes in mild steel and sheet metal without secondary finishing
• 3/4 inch Weldon shank fits most small and large magnetic drill presses with correct arbor
• Compatible pilot pin: 49-59-0012 for accurate centering during use

Compatibility

Designed for use with magnetic drill presses equipped with a 3/4 inch Weldon shank arbor. Intended for mild steel applications including sheet metal and plate stock. Use with pilot pin 49-59-0012 as specified by the manufacturer.

Installation Notes

Installation and use should be performed by qualified trade professionals familiar with magnetic drill press operation. Secure the workpiece and verify the magnetic drill press base is firmly engaged before beginning the cut. Always insert the pilot pin before drilling to prevent cutter wander and ensure hole accuracy. Wear appropriate PPE including eye protection and cut-resistant gloves when operating rotary cutting tools on steel.
