The MILWAUKEE 49-59-4094 is a tungsten carbide tipped (TCT) annular cutter engineered for fast, burr-free hole cutting in hard metal materials. It features an advanced tooth geometry that simultaneously cuts, cleans, and clears chips while drilling, reducing heat buildup and extending cutter life. The thin-wall design displaces less material than standard twist-drill methods, producing cleaner holes in less time. With a 15/16 inch cutting diameter and a 3/4 inch Weldon shank, this cutter is compatible with most small and large magnetic drill presses. It is used by electricians, ironworkers, fabricators, and mechanical contractors working on structural steel, stainless steel, and cast iron.
The 49-59-4094 is suited for hard metal applications including stainless steel and cast iron where conventional drill bits struggle. It fits magnetic drill presses accepting a 3/4 inch Weldon shank. Larger magnetic drill presses can use this cutter with the appropriate arbor. The cutter ships as a single unit and is designed for repeated, production-level hole-making in shop and field environments where clean, precise holes are required without secondary deburring.
Designed for use with magnetic drill presses equipped with a 3/4 inch Weldon shank arbor. Compatible with most small magnetic drill presses; larger magnetic drill presses require the correct arbor adapter. Recommended pilot pin: 49-59-0014.
Installation and operation should be performed by qualified tradespeople familiar with magnetic drill press equipment and metal fabrication practices. Secure the workpiece firmly and verify the magnetic drill press is properly seated and energized before beginning the cut. Power down and de-energize the drill press before changing cutters or inserting the pilot pin. Always use cutting fluid appropriate for the base metal to maximize cutter life and hole quality.
