You don’t have to move your hand from the handle to switch bits, making it a more convenient way to manage it. It’s especially helpful when you’re working at height or in areas where there’s no easy place to set the tool down. Additional Features This compact impact driver tips the scales at 2 pounds, even. Adding the recommend 2.5Ah battery brings that number up to 3.4 pounds. It measures 5 inches from tip to tail, but the big deal here is that the head only 2-1/2 inches wide. The slim profile allows you to work in tight spaces where larger tools may not fit. We also wanted to test it on our Inertia Torque impact torque tester. However, there’s so much power behind the hammer and anvil, that it just snapped our 1/2-inch square adapters like they were made of plastic. Flex 24V Brushless Impact Driver Design Notes Size and Weight

Flex finished with a 5-test average of 6.13 seconds. Of the impact drivers we’ve tested so far, only Milwaukee’s Gen 3 M18 Fuel had a faster time (5.84 seconds). Aside from that, the third-place finisher was more than a second slower.

To see how Flex dialed all that in, we put it to work in our RSS test to see how it handle large structural fasteners. Using 8-inch RSS screws from GRK Fasteners, we drove it into layered OSB subfloor. No, that’s not a “normal” application, but OSB is really consistent so it makes a good material when you’re comparing tools the way we do. Kenny’s life around power tools started early. His grandfather was an airplane mechanic in WW2 and took up woodworking as a hobby after retiring from the power industry. Building everything from bookshelves to lazy Susans, he became extremely accomplished while his young grandson observed, fascinated at the way raw wood could turn into something both beautiful and functional. In fact, Kenny still uses several pieces that his grandfather made more than 30 years ago.

The standard warranty is 5 years for both the battery and the tool. However, if you register the tool, battery, and charger by December 31, 2022, you get a lifetime warranty for all of them under the Flex Founders program. The Bottom Line
