Milwaukee 49-59-4138 Tct Annular Cutter 1-3/8 in

Product Description

The MILWAUKEE 49-59-4138 is a tungsten carbide tipped (TCT) annular cutter designed for fast, clean hole cutting in hard metal materials. Its advanced tooth geometry cuts, cleans, and clears chips simultaneously during drilling, reducing heat buildup and extending tool life. The thin-wall design displaces less material than standard hole cutters of the same diameter, producing burr-free holes in demanding materials such as stainless steel and cast iron. At 1-3/8 inches in diameter and 3.65 inches in length, this cutter is sized for a wide range of structural and fabrication applications. It is installed and operated by licensed electricians, ironworkers, pipefitters, and metal fabricators who require consistent hole quality in production or field settings.

This annular cutter is built for use in hard metal applications including stainless steel and cast iron where standard twist drills struggle or fail prematurely. It fits a 3/4-inch Weldon shank, making it compatible with most small and large magnetic drill presses when used with the appropriate arbor. It is well-suited for structural steel work, pipe fabrication, electrical panel fabrication, and mechanical room installations where clean, precise holes are required in heavy-gauge metal.

Key Features

• Advanced tooth geometry cuts, cleans, and clears material simultaneously during drilling for faster hole completion
• Thin-wall design removes less material per hole, increasing cutting speed and reducing motor load on the drill press
• Tungsten carbide tipped construction extends tool life in stainless steel, cast iron, and other hard metals
• 3/4-inch Weldon shank fits most small and large magnetic drill presses with correct arbor
• Produces burr-free holes, reducing or eliminating secondary deburring steps
• Compatible with pilot pin 49-59-0014 for center-point accuracy during setup

Compatibility

Designed for use with most small and large magnetic drill presses equipped with a 3/4-inch Weldon shank arbor. Use with pilot pin 49-59-0014. Suitable for hard metal materials including stainless steel and cast iron.

Installation Notes

Installation and operation should be performed by qualified tradespeople familiar with magnetic drill press equipment and metal cutting safety practices. Ensure the magnetic drill press is firmly secured to the workpiece and the base has full surface contact before energizing the magnet or beginning the cut. Always insert the correct pilot pin before starting to prevent walking at hole entry. Wear appropriate PPE including eye protection and gloves when operating annular cutters in metal fabrication settings.
