The Black and Decker 3.6 -volt Lithium Ion Smartdriver redefines what a cordless screwdriver should be. Featuring an exclusive patented retractable screw-holder with magnetic tip that prevents you from dropping screws, you can easily drive screws with one hand. A well marked forward/reverse window makes it easy to control which direction is selected and an innovative 6-position clutch prevents from stripping of screws. A built-in LED work light provides good visibility when working in dark areas. Lithium-Ion battery technology means that the LI4000 stays charged and ready for use for up to 18-months and features a LED charging indicator light for peace of mind. A wall-mountable/table-top charging case is included.
