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 that weighs only 2.8 lbs., with two speed settings and 350 in. lbs. of max torque. The variable speed brushless impact driver weighs only 2.6 lbs. with two speed settings and 1,240 in. lbs. of max torque. 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. It is part of Makita's expanding 18-Volt Lithium-Ion series, the world's largest cordless tool line-up powered by 18-Volt Lithium-Ion slide-style batteries. Makita 18-Volt Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger.
