The Makita 18-Volt LXT Lithium-Ion Brushless Cordless Quick-Shift Mode 3-Speed Impact Driver (model XDT14Z, tool only) is a top-notch solution for fastening tasks. It offers users increased torque, longer run-time, and precision features for precise fastening. The XDT14Z is compact and lightweight, providing a superior power-to-weight ratio. With a full 1,550 in. lbs. of fastening torque and category-leading precision features, this impact driver delivers exceptional performance. The Quick-Shift Mode is an automatic electronic controller that downshifts and reduces rotation and impact speed before driving the screw into place. This feature is designed to minimize screw thread stripping, screw breakage, and damage to the work. For faster tightening of self-drilling screws, the Tightening Mode (T-mode) can be used to prevent damage to the screw or workpiece. These precision settings, combined with the 3-speed power settings, give users more control for a wide range of fastening tasks, from cabinet screws to lag bolts. The compact size of the XDT14Z, measuring only 4-5/8 in. long, makes it ideal for work in tight spaces. The impact driver is equipped with Star Protection, a communication technology that allows the tool and battery to exchange data in real-time, monitoring conditions during use to protect against overloading, over-discharging, and overheating. Additionally, the XDT14Z can be powered by Makita 18-Volt LXT and Compact Lithium-Ion batteries with the star symbol, indicating Star Protection inside, for increased versatility.
