Milwaukee 49-56-0744 Carbide Hole Saw 4-1/2 Inches

Product Description

The Milwaukee Electric Tool Corp 49-56-0744 is a 4-1/2-inch carbide hole saw engineered for cutting through extreme and hard materials where standard bi-metal saws fail prematurely. Carbide teeth deliver up to 50 times longer life compared to standard designs, making this saw a reliable choice for demanding trade applications. A 4 TPI carbide tooth geometry maximizes durability and extends service life in stainless steel and other difficult substrates. A thermoset coating reduces friction drag across the cut, improving overall cutting speed and supporting efficient cordless tool operation.

This hole saw is suited for electricians, plumbers, HVAC technicians, and general contractors working in commercial and industrial environments where stainless steel panels, thick gauge metals, or other extreme materials are encountered. The Plug-Jack T-Slot design improves access and leverage when removing material slugs from the cup, reducing downtime during high-volume drilling tasks. It is sold as a unit quantity of 2 per package, making it practical for stocking a service vehicle or job-site kit.
