Milwaukee 49-59-4125 Tct Annular Cutter 1-1/4 in Hard Metal

Product Description

The MILWAUKEE 49-59-4125 is a tungsten carbide tipped (TCT) annular cutter designed for drilling clean, fast holes in hard metal materials. It features a 1-1/4 inch cutting diameter and a 3/4 inch Weldon shank, making it compatible with most small and large magnetic drill presses when used with the appropriate arbor. The advanced tooth geometry cuts, cleans, and clears chips simultaneously during the drilling stroke, reducing heat buildup and extending cutter life. The thin-wall construction displaces less material than a standard twist drill or competing annular cutters of the same diameter, delivering burr-free holes more efficiently. Licensed trades and metalworking professionals rely on this cutter for structural steel, stainless steel, and cast iron applications.

This cutter is suited for hard metal applications in both shop and field environments where a magnetic drill press is the primary tool. Common use cases include fabrication work, structural steel erection, pipe fitting, and mechanical contracting where precise, clean holes are required in ferrous and difficult alloys such as stainless steel and cast iron. The 3/4 inch Weldon shank provides positive engagement in the arbor chuck, minimizing slippage under the torque loads generated in hard material drilling. This cutter is sold as a single unit and is intended for use with ejector pin 49-59-0014.

Key Features

• Advanced tooth geometry cuts, cleans, and clears material simultaneously for faster hole completion
• Thin-wall design removes less material than solid-core drilling, increasing hole speed and reducing load on the drill press
• 1-1/4 inch cutting diameter delivers burr-free holes in a single pass
• 3/4 inch Weldon shank fits most small and large magnetic drill presses with the correct arbor
• Rated for hard metal applications including stainless steel and cast iron
• Compatible ejector pin: 49-59-0014

Compatibility

Designed for use with most small magnetic drill presses and large magnetic drill presses equipped with the correct arbor accepting a 3/4 inch Weldon shank. Use with ejector pin 49-59-0014.

Installation Notes

Installation and operation should be performed by qualified metalworking or mechanical trade professionals familiar with magnetic drill press operation. Secure the workpiece and confirm the magnetic base has full, flat contact with the material before energizing the magnet and beginning the cut. Inspect the Weldon shank seating and arbor set screws before each use to ensure positive drive engagement. Always wear appropriate PPE including eye protection and cut-resistant gloves when operating annular cutters in hard metal.
