Milwaukee 49-56-0023 Bi-metal Hole Saw 3/4 Inch

Product Description

The Milwaukee Electric Tool 49-56-0023 is a 3/4-inch bi-metal hole saw designed for general-purpose cutting in metal, wood, and composite materials. It uses a 3.5 TPI tooth geometry engineered for extended tooth life in metal applications. The thermoset coating reduces friction during the cut, which helps maintain blade temperature and is optimized for use with cordless tools. An all-access slot design speeds up plug removal between cuts and improves pilot bit visibility for accurate hole placement. Faster chip ejection keeps the cut cooler and reduces downtime. This saw is suited for installation work performed by electricians, plumbers, HVAC technicians, and general contractors.

The 49-56-0023 is intended for general-purpose drilling applications across residential and light commercial jobsites. Its 3/4-inch cutting diameter fits common trade applications such as conduit knockouts, pipe penetrations, and junction box openings. The all-access slot design is particularly useful in repetitive-hole drilling tasks where plug removal and repositioning speed directly affect productivity. The thermoset coating provides performance benefits when paired with cordless drill drivers, delivering more holes per battery charge compared to uncoated bi-metal saws.
