Recommended by Scott Strollo, Pro Tool Reviews

For residential furnace and water heater installs, sometimes a pro needs a good pipe wrench, and Rigid and Milwaukee are the go-to brands.

It’s considerably lighter than the steel alternatives but delivers the needed amount of power.

“I like everything about the Milwaukee 18-inch aluminum pipe wrench,” he writes in his review for Pro Tools. “The lightweight, the dual coil springs, the handle length and comfort, and gripping force of the overbite jaws. I certainly recommend it to other Pros.”
