Milwaukee 49-56-0127 Bi-metal Hole Saw 2-1/8 Inches

Product Description

The Milwaukee Electric Tool Corp 49-56-0127 is a 2-1/8 inch bi-metal hole saw designed for general-purpose cutting in metal, wood, and composite materials. Built with a 3.5 TPI tooth geometry, this hole saw is engineered for extended tooth life in demanding metal applications. A thermoset coating reduces friction during the cut, which translates to faster cutting speeds and optimized performance on battery-powered tools. All-access slots on the body allow for straightforward plug removal without extra tools, reducing downtime between holes and keeping the pilot bit visible for accurate placement. Licensed contractors, electricians, and plumbers rely on this saw for conduit knockouts, pipe penetrations, and panel work.

This hole saw is suited for residential and commercial applications where repeated cuts through sheet metal, steel plate, wood framing, or plastic are required. The 3.5 TPI design handles both thin-gauge and thicker stock, making it a practical option for electrical rough-in, plumbing penetrations, and HVAC ductwork. The thermoset coating is specifically optimized for cordless drill and driver use, maintaining cut quality as battery voltage tapers. Compatible arbors include TV 138-923 and TV 139-793 as specified by the manufacturer.
