How to Choose the Best Cordless Impact Wrench
Torque is the headline spec, but read it carefully: breakaway (nut-busting) torque loosens stuck fasteners, while fastening torque is what it tightens to, and the two differ a lot. For automotive lug nuts, a 1/2-inch anvil with 300-plus foot-pounds covers nearly everything; heavy truck and equipment work wants more. A brushless motor delivers that power with better runtime and longevity. Pay close attention to the battery platform, since a ‘bare tool’ that runs on packs you already own saves real money, while a kit bundles batteries and a charger. Multiple torque or control modes help you avoid snapping smaller bolts. Weight and length matter if you’ll work in tight engine bays or overhead. Balance the torque you actually need against battery compatibility and size, and the best cordless impact wrench will handle stuck bolts for years without an air compressor.
