The SD Driver with Screw Holder is for professionals or DIY-ers that have a lot of work to get done. Using a manual screwdriver can strain your hands pretty quickly, and everyone drops fasteners and bits on the ground. Eliminate those two problems with this semi-automatic driver and bit changer-with a screw holder built right in. You just press the orange button on the tip to get the jaws to accept the screw. Then with just one hand, you can maneuver into tight spaces and drill it home. The jaws work when you need to back screws out, too. Your six favorite bits are stored onboard, and you cycle between them by shifting the top piece back towards you. With 0-230 revs/min of no-load speed, you?ll have enough torque to handle the most common screwdriver applications. And the LED headlamp lets you see what you?re doing, even in the dark. The internal 4V battery will hold a charge for up to 18 months, so you can toss the SD Driver on a shelf and it?ll be ready to go the next time you pick it up. A charger comes with it, as does the reloadable bit cartridge, which is stocked with 6 of the most common bits already. Save your hands and stop losing bits and fasteners. Get screws into places you never thought possible before. The SD Driver with Screw Holder is a solution to a couple of problems that come with using a regular screwdriver. Luckily, you don?t have to worry about those anymore.
