Put together ready-to-assemble furniture three times faster than manual screwdriving with the Cordless Furniture Assembly Tool / Screwdriver. 4V/ 1.5 Ah battery is enough power and runtime for common furniture assembly applications. Features 180 rpm and 40 In./Lb. of torque. Place the hex wrench that comes with furniture into the chuck to turn it into a powered hex wrench. The magnetic hex key alignment helps ensure the hex key is aligned in the jaws of the chuck. Use the included screwdriving bits to handle other tasks around the house. Compact, lightweight design is easy to use and helps access smaller surfaces. Multiple position trigger for use with either two fingers or one. An integrated LED (light emitting diode) light helps illuminate poorly lit locations such as inside cabinets and under tables. Includes micro USB (universal serial bus) charging cable, 4 mm hex wrench, (5) general purpose screwdriver bits: PH1, PH2, SL4, SL8, SQ4.
