Milwaukee 49-56-0012 Bi-metal Hole Saw 5/8 Inch

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 49-56-0012 is a 5/8-inch bi-metal hole saw designed for general purpose cutting in metal and other common construction materials. It features a 3.5 TPI tooth geometry engineered to extend tooth life in metal applications. A thermoset coating on the saw body reduces friction during the cut, which improves cutting speed and lowers heat buildup. The All-Access slots built into the body address one of the most common frustrations in hole saw work: plug removal. Those same slots increase pilot bit visibility for accurate hole placement and improve chip ejection to keep the cut cooler. Licensed tradespeople and skilled installers working in metal fab, electrical rough-in, and mechanical system installation will find this saw suited to production-rate use.

The 49-56-0012 is appropriate for residential and light commercial applications where frequent hole sawing through metal, wood, and composite materials is required. The thermoset coating is specifically optimized for cordless tool use, delivering roughly 25 percent more holes per battery charge compared to uncoated designs. This makes it practical on job sites where returning to a charging station frequently is not an option. The All-Access slot design reduces downtime between holes by making plug removal faster without additional tools.
