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

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 49-56-0043 is a 1-inch bi-metal hole saw built for trade professionals who cut through metal, wood, and multi-material substrates on a regular basis. It features a 3.5 TPI tooth geometry designed to extend tooth life in metal applications. A thermoset coating on the blade reduces friction during the cut, which translates to faster cutting speeds and improved performance when running on cordless tools. All-access slots are machined into the body to simplify plug removal, reduce downtime between holes, and improve pilot bit visibility for accurate placement. Chip ejection is enhanced by the slot design, helping keep the cut zone cooler during extended use.

This hole saw is suited for general-purpose applications across residential and commercial jobsites. Electricians, plumbers, HVAC technicians, and general contractors use this size to cut chase openings, conduit penetrations, and service access holes in sheet metal, wood framing, and similar materials. The 1-inch diameter makes it a common choice for single-trade rough-in work where a compact, clean-bore hole is required. It is optimized for use with cordless drills and drivers, and the thermoset coating is specifically formulated to deliver consistent performance per battery charge.
