Milwaukee 49-59-2056 Hss Annular Cutter 9/16 in Sheet Metal

Product Description

The MILWAUKEE 49-59-2056 is a high speed steel (HSS) annular cutter designed for fast, clean hole cutting in mild steel and sheet metal applications. Built with a thin-wall construction and advanced tooth geometry, this cutter simultaneously cuts, cleans, and clears material as it drills. The result is burr-free holes produced faster and with less material displacement than conventional twist drill bits. The 3/4 inch Weldon shank makes it compatible with most small and large magnetic drill presses, with the appropriate arbor for larger machines. Metalworkers, fabricators, and maintenance technicians rely on this cutter for production and field work alike.

This annular cutter is sized at 9/16 inch diameter with a 3.386 inch cutting length, making it well suited for drilling clean through-holes in sheet metal and mild steel plate. It is designed for use in magnetic drill press setups commonly found in structural steel fabrication, HVAC ductwork shops, and general metal fabrication environments. The thin-wall geometry reduces the force required to complete a hole, improving operator control and extending cutter life in repetitive drilling operations.

Key Features

• Advanced tooth geometry cuts, cleans, and clears material simultaneously during drilling
• Thin-wall design removes less material for faster hole completion and reduced heat buildup
• Produces burr-free holes without secondary deburring in most mild steel applications
• 3/4 inch Weldon shank fits most small magnetic drill presses and large presses with a compatible arbor
• Rated for mild steel applications including sheet metal and plate
• Compatible with pilot pin 49-59-0012 for accurate hole positioning

Compatibility

Fits magnetic drill presses with a 3/4 inch Weldon shank arbor. For use with pilot pin 49-59-0012. Designed for mild steel and sheet metal cutting applications.

Installation Notes

Installation and use of this cutter should be performed by qualified metalworkers or trade professionals familiar with magnetic drill press operation. Secure the workpiece and confirm the magnetic drill base is fully engaged before beginning a cut. Ensure the Weldon shank is fully seated and the set screw is tightened in the arbor before operation. Always use appropriate cutting fluid for mild steel to extend cutter life and reduce heat.
