OK, it's not Friday night, but we recently did a Friday Night Tool fight between the Dewalt, Milwaukee and the Metabo cordless Jig Saws. All of these Jig Saws are sold as bare tools or in a kit. The model number on the Milwaukee is 2645-22, Metabo STA 18LT and the Dewalt is DCS331.
We tested each Jig Saw with a 4 A/h battery. We used Bosch Jig Saw wood blades to cut through a 2×4. We wanted to see how many feet we could get off each fully charged battery. Next we did a quick scrolling test to see which one felt better. You can check out the video below to see how each one faired.
