You won’t find a variable-speed trigger or a forward/reverse switch on DeWalt’s new variable-speed reversible 8V MAX Gyroscopic Screwdriver (DCF680). Instead, the tool uses “gyroscopic technology” to sense the motion of your gripping hand. After pressing the trigger, you simply twist the tool clockwise for forward or counterclockwise for reverse. The farther you twist in either direction — from top-dead-center to 35 degrees — the faster the speed (until you top out at 430 rpm). A lock-off prevents accidental activation. The 1.1-pound tool also has a two-position inline/pistol grip, a 1/4-inch quick-change hex chuck for 1-inch bit tips, an LED headlight, and a battery gauge. DeWalt product manager Jim Watson tells us the tool is ideal for light-duty install and maintenance — like mounting cabinet hardware or accessing electrical panels — with enough power to fully sink a 1 5/8-inch wood screw into pine. Kits will be available in August and cost $90 with one battery or $100 with two. — B.G.
