Milwaukee 49-59-2163 Hss Annular Cutter 1-5/8 in Dia

Product Description

The MILWAUKEE 49-59-2163 is a high speed steel (HSS) annular cutter engineered for fast, clean hole-cutting in mild steel and sheet metal. Built with a thin-wall construction and advanced tooth geometry, the cutter removes material efficiently while simultaneously cleaning the bore during drilling. The result is burr-free holes with less material displacement compared to standard twist drills or hole saws. The cutter measures 1-5/8 inches in diameter and 3.386 inches in length, and it ships with a 3/4-inch Weldon shank that fits most small and large magnetic drill presses. Licensed HVAC, plumbing, and electrical tradespeople use this cutter for sheet metal penetrations and structural steel work on job sites.

The 49-59-2163 is suited for mild steel applications ranging from light-gauge sheet metal to thicker plate stock. Its thin-wall design reduces the volume of material displaced per hole, which translates directly to faster cycle times and less heat buildup at the cutting edge. The 3/4-inch Weldon shank is the industry-standard interface for magnetic drill press arbors, making this cutter compatible with a wide range of portable magnetic drills when used with the appropriate arbor. It is a practical choice for mechanical, plumbing, and electrical contractors who need consistent, repeatable holes in steel framing, enclosures, or panel knockouts.

Key Features

• Advanced tooth geometry cuts and cleans the bore simultaneously, reducing burrs and secondary finishing work
• Thin-wall design displaces less material per hole for increased cutting speed and reduced heat
• 1-5/8 inch cutting diameter for standard trade applications in sheet metal and mild steel plate
• 3/4-inch Weldon shank fits most small and large magnetic drill presses with the correct arbor
• Use with pilot pin 49-59-0012

Compatibility

Designed for use with magnetic drill presses equipped with a 3/4-inch Weldon shank arbor. Pilot pin 49-59-0012 is recommended for use with this cutter. Intended for mild steel applications.

Installation Notes

Installation of annular cutters is typically performed by licensed tradespeople using a compatible magnetic drill press. Secure the workpiece and verify the magnetic base has full, firm contact with the steel surface before drilling. Always use cutting fluid or lubricant to extend cutter life and reduce heat buildup. Inspect the Weldon shank set-screw engagement before each use to confirm the cutter is fully seated in the arbor.
