The XDT14Z combines a full 1,550 In./Lb. of fastening torque with category-leading precision features. Quick-Shift Mode uses the brushless motor electronic controls to find the best balance of speed and torque for each application for more efficient fastening. Another precision feature is Tightening Mode (T-mode), which downshifts and reduces rotation and impact speed prior to driving the screw into place, and is engineered to minimize screw thread stripping, screw breakage and damage to work. These precision features, combined with 3-speed power settings, give users more control for a wide range of fastening tasks from cabinet screws and deck screws to lag bolts, and much more. It is only 4-5/8 In. long and ideal for work in tight spaces. Tool Only - battery and charger not included.
