New! Powerful and compact with 4 speed settings and a range of fastening modes for categoryleading performance. has a legacy of innovation in the cordless impact driver category and the 18V LXT Brushless 4-Speed Impact Driver XDT16Z sets new standards. The XDT16Z offers users four speeds as well as s exclusive Quick-Shift Mode for increased fastening control. Quick-Shift Mode uses the brushless motors electronic controls to find the best balance of speed and torque for each application for more efficient fastening. Another precision setting 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. The XDT16Z delivers industry-leading performance in a compact and ergonomic design. Added features include the one-touch 4-speed power selector button under the chuck which enables one-handed speed changes and reverse rotation auto-stop mode which stops rotation and impact when the fastener is loosened adequately to help prevent over-loosening and dropped fasteners. For improved tool performance and extended battery life created Star Protection Computer Controls. Star Protection is communication technology that allows the Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading over-discharging and overheating. For increased versatility the tool can also be powered by 18V LXT and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside.
