Milwaukee 49-56-0043 Bi-metal Hole Saw 1 Inch

Product Description

The MILWAUKEE 49-56-0043 is a 1-inch bi-metal hole saw built for general-purpose cutting in metal and other common trade materials. It uses a 3.5 TPI tooth geometry engineered for extended tool life in metal applications. A thermoset coating reduces friction during the cut, which keeps temperatures lower and improves compatibility with cordless tool platforms. The all-access slots built into the cup address one of the most common field complaints with hole saws: plug removal. Faster plug ejection means less downtime between holes on the job. This saw is manufactured in the USA.

This hole saw is suited for residential and commercial trade work across HVAC, electrical, and plumbing disciplines. Typical applications include cutting conduit knockouts, pipe penetrations through framing or light-gauge metal, and panel openings. The 1-inch cut diameter fits a range of common rough-in and penetration tasks. The all-access slot design also improves pilot bit visibility during placement, which reduces layout errors and the need for repositioning on finished or painted surfaces.
