It can make tire rotations, brake jobs, suspension work, rusty hardware, stubborn lug nuts, and other high-effort jobs much easier than fighting everything with a breaker bar. Even outside the garage, a cordless impact wrench can help with equipment repairs, trailers, lawn gear, heavy hardware, and projects where a normal drill or impact driver doesn't have enough muscle.Right now, the Tasfit 1/2-Inch Cordless Impact Wrench is on sale at Amazon for $70, over 40% off its normal $120 price. This is a tool-only model, so the battery and charger are not included, but that can be a plus for anyone who already owns compatible DeWalt 20V batteries. Instead of buying into another platform, you can add a budget-friendly cordless impact wrench that works with batteries you may already have in the garage or work truck.Tasfit 1/2-Inch Cordless Impact Wrench, $70 (was $120) at AmazonTasfit 1/2-Inch Cordless Impact Wrench, $70 (was $120) at AmazonCheck PriceIt offers up to 1,110 pound-feet of breakaway torque, which is serious output for a cordless impact at this price. That makes it useful for loosening stubborn lug nuts, rusted bolts, over-tightened fasteners, and other hardware that can turn a simple automotive repair into a long afternoon. The brushless motor is designed for better runtime, lower heat, and stronger performance than a traditional brushed motor, which is helpful if you use the tool often.AdvertisementAdvertisementThe three-speed control gives you 1500, 1800, and 2200 rpm settings, while the variable trigger lets you ease into the power instead of going full blast every time. It also has forward and reverse modes, plus a reverse auto-stop function that stops once a nut or bolt is loosened to help prevent fasteners from spinning off. Great for tire changes, auto repair, garage projects, heavy-duty fastening, and anyone already sitting on DeWalt-compatible batteries, this is a heck of a deal.Related: Amazon Is Selling a 1/2-Inch Cordless Impact Wrench for $59, and Shoppers Say It's 'Better Than Name Brand' Options "Easy to use, carry, and operate," said one happy user.
