Milwaukee 49-59-1375 Hss Annular Cutter 1-3/8 in Sheet Metal

Product Description

The MILWAUKEE 49-59-1375 is a high speed steel (HSS) annular cutter designed for cutting clean, precise holes in sheet metal and mild steel plate. It features a thin-wall construction paired with an advanced tooth geometry that cuts, clears, and cleans debris in a single pass, reducing cycle time and extending tool life. The cutter measures 1-3/8 inches in diameter and 2.358 inches in length. It ships with a 3/4-inch Weldon shank, making it compatible with most small magnetic drill presses and large magnetic drill presses when paired with the appropriate arbor. Installed by metalworkers, ironworkers, and sheet metal mechanics on job sites and fabrication floors.

This annular cutter is suited for residential and commercial sheet metal work, structural steel fabrication, and general mild steel drilling applications. Its thin-wall design displaces less material than conventional twist bits or hole saws, producing fast, burr-free holes without requiring a secondary deburring step. Typical applications include panel drilling, steel framing, equipment mounting, and conduit or pipe penetrations through steel members. For pilot pin use, pair with pin 49-59-0011.

Key Features

• Advanced tooth geometry cuts, cleans, and clears material simultaneously for faster hole completion
• Thin-wall design removes less material per pass, increasing cutting speed and reducing heat buildup
• 3/4-inch Weldon shank fits most small and large magnetic drill presses with the correct arbor
• Produces burr-free holes in sheet metal and mild steel without secondary finishing
• Compatible with pilot pin 49-59-0011 for accurate hole positioning

Compatibility

Designed for use with magnetic drill presses accepting a 3/4-inch Weldon shank. Large magnetic drill presses require the correct arbor adapter. Intended for mild steel applications including sheet metal and plate steel.

Installation Notes

This cutter is installed and operated by metalworkers, ironworkers, and sheet metal mechanics. Secure the workpiece fully before engaging the magnetic drill press, and confirm the magnet has proper surface contact before beginning the cut. Always use cutting fluid or lubricant on the cutter to reduce heat and extend tool life. Disengage power and allow the cutter to come to a complete stop before changing tooling or clearing chips.
