The 18V LXT Brushless 2-piece combo kit (XT268T) gives you two brushless solutions with more performance features for drilling, driving and fastening. Each tool features an efficient Makita BL brushless motor that is electronically controlled for longer run time, increased power and speed, and longer tool life. The combo kit includes a hammer driver-drill with a full 1090 inch-lbs of max torque for the most demanding applications in wood, metal and masonry. The kit also includes an efficient and compact impact driver that combines a full 1,550 inch-lbs of fastening torque with category-leading precision features. Quick-shift mode is an automatic electronic controller that downshifts and reduces rotation and impact speed prior to driving the screw into place, and is engineered to minimize screw thread stripping, breakage and damage to work. For faster tightening of self-drilling screws, the tightening mode (T-mode) is engineered to prevent damage to the screw or work piece. These precision features, combined with 3-speed power settings, give users an impact driver with more control for a wide range of fastening tasks from cabinet screws and deck screws to lag bolts, and much more. The 18V LXT lithium-ion 5.0Ah batteries have the fastest charge times in their category, and for increased convenience they include an on-board LED charge level indicator.
