Milwaukee 49-56-0237 Bi-metal Hole Saw 4-3/4 Inches

Product Description

The Milwaukee Electric Tool Corp 49-56-0237 is a 4-3/4 inch bi-metal hole saw designed for demanding metal and general-purpose cutting applications. Built around a 3.5 TPI tooth geometry, this hole saw delivers extended blade life in metal while maintaining versatility across a range of materials. A thermoset coating reduces friction during the cut, which translates to faster cutting speeds and optimized performance on cordless tools. Licensed tradespeople and experienced installers working in electrical, HVAC, plumbing, and construction trades rely on this style of hole saw for precise, repeatable through-cuts in metal panels, junction boxes, pipe penetrations, and similar tasks.

This hole saw is suited for residential and commercial job-site use wherever a 4-3/4 inch diameter hole is required. The all-access slots along the body allow straightforward plug removal without additional tools, reducing downtime between cuts. The slot design also improves pilot bit visibility for accurate hole placement and promotes faster chip ejection, helping keep cut temperatures lower during extended use. Sold as a package of 2 units per order.
