The 18-Volt LXT 2-Piece Combo Kit (XT296SMR) delivers two premium brushless tools for drilling, driving, and fastening. The Kit includes two fast-charging 18-Volt LXT batteries (one 2.0Ah Battery (BL1820B) and one 4.0Ah Battery (BL1840B)), which are compatible with the full range of Makita tools and products. The kit includes an 18-Volt LXT Brushless 4-Speed Impact Driver (XDT14Z), that combines power and speed in a compact size. The XDT14 delivers 1,550 in. lbs. of Max Torque and weighs only 2.7 lbs. with a 2.0Ah battery, with a 3-speed power selection switch (0-1,100 / 0-2,100 / 0-3,600 RPM and 0-1,100 / 0-2,600 / 0-3,800 IPM) and Makita's exclusive Quick-Shift Mode for increased fastening control. Quick-Shift Mode uses the brushless motor's 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 18-Volt LXT Brushless Variable 2-Speed Hammer Driver-Drill (XPH16Z) combines power and run-time for more drilling, driving, and fastening tasks in wood, metal, and masonry. This promotion also comes with a bonus E-01644 IMPACT XPS Alloy Steel Impact Rated Screwdriver Drill Bit Set (60-Piece).
