The 18V LXT Lithium-Ion Brushless 2-Piece Combo Kit (XT288T) delivers two premium brushless tools for drilling, driving, and fastening. The Kit includes two fast-charging 18V LXT 5.0Ah batteries, which are compatible with the full range of Makita LXT tools and products. The Kit includes the 18V LXT Brushless 4-Speed Impact Driver (XDT19), offering 4-speed power selections (0-1,100/ 0-2,100/ 0-3,200/ 0-3,600 RPM & 0-1,100/ 0-2,600/ 0-3,600/ 0-3,800 IPM) which provides precise fastening control for a wide range of applications. The Impact Driver features Assist Mode (A-mode) which helps eliminate "screw cam-out" and "cross threading" by driving at low speed until tightening begins. It also features two Tightening Modes (T-mode) for faster tightening of self-drilling screws in thick or thin gauge metal that helps prevent damage to the screw or workpiece. Also included is the 18V LXT Brushless Variable 2-Speed Hammer Driver-Drill (XPH14) which combines power and run-time for more drilling, driving, and fastening tasks in wood, metal, and masonry. It delivers up to 2,100 RPM and a full 1,250 in.lbs. of Max Torque and weighs only 6.0 lbs. with battery. The XPH14 has a more compact and ergonomic design, up to 14% shorter than the previous model. It's powered by a Makita brushless motor for longer run time, increased power and speed, and longer tool life.
