The Makita 18V LXT Sub-Compact Brushless Combo Kit, No. CX200RB, combines 12V handling with 18V performance, run-time and compatibility. An 18V battery from any Makita LXT tool will power the 18V Sub-Compact driver-drill and impact driver. The kit includes an ultra-compact two-speed brushless driver-drill that weighs 2.8 lbs., and a variable speed brushless impact driver with two speed settings that weighs 2.6 lbs. 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.
