When the inquisitive engineers at Milwaukee Tools started asking professional carpenters what they wanted in a portable circular saw, they consistently heard the same three things: pure cutting power, maximum control, and all-day comfort. The result of their research went into the creation of the Milwaukee 6391-21, arguably the best-built circular saw on the market.
For starters, the 6391 has a monster 15-amp, 5,800-rpm motor that produces 3-1/4 horsepower; thats nearly as powerful as a worm-drive saw, yet this 7-1/4-inch Milwaukee model is more than one third lighter.
Look closely and youll notice that the blade is mounted on the left side of the motor. That southpaw position gives right-handed users a much clearer view of the cutting line since they no longer have to lean over their arm to see the blade. The 10.4-pound saws thick aluminum shoe tilts up to 50 degrees for bevel cutting.
The 6391 is also equipped with Milwaukees exclusive Tilt-Lok handle that can be adjusted to the most comfortable cutting position: to the rear for vertical cutting, on top for horizontal cutting, or anywhere in between. The saw comes with a carbide-tipped saw blade, blade wrench, storage case and owners manual. -- Joseph Truini
