The Makita 18-Volt LXT® Lithium-Ion Sub-Compact Brushless Cordless 2-piece Combo Kit (CX200RB) lets users do more with less, with two ultra-compact cordless solutions for drilling, driving and fastening in a more compact size with significantly less weight. The 18-Volt Sub-Compact Driver-Drill and Impact Driver are a new class of compact, with the size and weight of lower voltage tools but with the performance, power and compatibility of 18-Volt. The expansive breadth-of-line of the Makita 18-Volt LXT® Series means an 18-Volt battery from any LXT® tool will power the 18-Volt sub-compact driver-drill and impact driver included in the CX200RB. The kit includes an ultra-compact 2-speed brushless driver-drill with two speed settings that weighs only 2.8 lbs., and a variable speed brushless impact driver with two speed settings that weighs only 2.6 lbs. For more efficient fastening, 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.
