Milwaukee 49-56-0147 Bi-metal Hole Saw 2-1/2 Inches

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 49-56-0147 is a 2-1/2 inch bi-metal hole saw built for demanding metal cutting applications in the trades. It features a 3.5 TPI tooth design engineered for extended tooth life when cutting through metal. A thermoset coating reduces friction during the cut, which improves cutting speed and helps the saw run cooler. The all-access slots built into the body allow for fast plug removal after each cut, reducing downtime between holes. Licensed electricians, plumbers, HVAC technicians, and general contractors will find this saw well-suited for repetitive hole cutting in sheet metal, conduit plates, and similar substrates.

This hole saw is a general-purpose cutting tool suited for residential and light commercial applications. It performs in situations where frequent hole cutting is required, including electrical rough-in, pipe penetrations, and HVAC duct work. The all-access slot design also improves pilot bit visibility during placement, allowing for more accurate hole positioning. The thermoset coating is optimized for use with cordless tools, delivering up to 25 percent more holes per battery charge compared to uncoated designs.
