Milwaukee 49-59-2131 Hss Annular Cutter 1-5/16 in Sheet Metal

Product Description

The MILWAUKEE 49-59-2131 is a high speed steel (HSS) annular cutter designed for cutting clean, accurate holes in sheet metal and mild steel plate. Its thin-wall construction displaces less material than standard hole cutters, resulting in faster drilling and reduced burring. The advanced tooth geometry cuts and clears chips simultaneously, extending tool life and improving hole quality. The cutter features a 3/4 inch Weldon shank, making it compatible with most small magnetic drill presses and larger units when paired with the appropriate arbor. Sold individually, it is the standard choice for electricians, ironworkers, pipefitters, and fabricators who need reliable, repeatable hole quality in steel.

The 49-59-2131 is suited for use in mild steel applications including structural steel fabrication, sheet metal work, electrical enclosure drilling, and general steel plate work. It is sized at 1-5/16 inch diameter, making it a common choice when precise hole sizing is required for conduit, bolt pass-through, or mechanical fastener installations. This cutter is intended for use with magnetic drill presses and requires the corresponding pilot pin 49-59-0012 for proper centering during operation.

Key Features

• Advanced tooth geometry cuts and cleans material simultaneously for faster, cleaner holes
• Thin-wall design removes less material per pass, increasing hole speed and reducing heat buildup
• 3/4 inch Weldon shank fits most small and large magnetic drill presses
• Produces burr-free holes in sheet metal and mild steel plate
• Use with pilot pin 49-59-0012 for accurate centering

Compatibility

Designed for use with magnetic drill presses accepting a 3/4 inch Weldon shank. Larger magnetic drill presses require the correct arbor adapter. Use with pilot pin 49-59-0012 as specified by the manufacturer.

Installation Notes

Installation is performed by licensed tradespeople or qualified fabricators using a magnetic drill press. Secure the workpiece fully before beginning any cut and confirm the magnetic base is firmly engaged before applying power. Ensure the correct pilot pin is seated in the cutter before drilling to prevent walking at the start of the cut. Always follow applicable shop safety protocols and wear appropriate PPE when operating drilling equipment.
