The HART 20V ½-inch Impact Wrench is a great, new addition for DIY mechanics. It's strong, with a powerful motor that can handle tough tasks, like tightening or loosening big nuts and bolts and delivering up to 350 ft/lbs. of torque. You can easily change sockets thanks to the friction ring, and the built-in LED light helps you see better in tight spots under your car's hood. Plus, it uses the same HART 20V Lithium-Ion Battery as other HART tools, so you can expand your tool collection without buying more batteries and chargers. (Battery and Charger Not Included).
