The PowerSmart 1/2 in. Compact Impact Wrench with Friction Ring delivers the best power to weight ratio, most access in tight spaces, and faster removal speed. It provides 265 ft. lbs. of nut-busting torque and only weighs 3.8 lbs., making it extremely versatile, capable of performing a wide variety of applications. Its PowerSmart Brushless Motor generates the power needed to quickly perform many tasks, such as removing large bolts or lug nuts. This cordless impact wrench is the most compact in its class, giving users access to stubborn fasteners in spaces where larger impact wrenches can't fit without needing to disassemble components to reach bolts. 3-Mode DRIVE CONTROL offers greater precision with a range of RPM and IPM levels, selectable from a single button on the tool. By selecting Mode 3, AUTO SHUT-OFF control applies no more than 35 ft. lbs. of torque for hand-tight fastening applications to prevent overtightening. Mode 3 also features Bolt Removal Control that delivers users full torque output, then decreases RPMs once the bolt is loosened to prevent fastener drops. The PowerSmart 4.0Ah battery pack fits all PowerSmart 20V tools, delivering more work per charge and more work over the life of the pack.
