Makita created a new class in cordless with 18V LXT Sub-Compact Tools. Makita Sub-Compact Products give users 12V handling with 18V performance, and compatibility with the world's largest 18V cordless tool system. The CX205RB is a combo kit with two 18V sub-compact solutions for drilling, driving and fastening in tight spaces. The kit includes an ultra-compact brushless hammer driver-drill and impact driver. The percussive hammer-drill setting allows for drilling into masonry and brick. It features two speed settings and a metal jampot design for durability. It delivers 350 in.lbs. of Peak Torque, speed up to 1,700 RPM and 25,500 BPM for a wide range of applications. The variable-speed brushless impact driver has two speed settings and delivers 1,240 in.lbs. of Max Torque. It features Assist Mode (A-mode), which helps eliminate "screw cam-out" and ""cross threading"" by driving at low speed until tightening begins. It's part of Makita 's expanding 18V LXT System, the world's largest cordless tool system powered by 18V lithium-ion slide-style batteries. Makita 18V LXT Lithium-Ion Batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. For improved tool performance and extended battery life, Makita created Star Protection Computer Controls . Star Protection is communication technology that allows the-Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18V LXT Lithium-Ion Batteries with the-Star symbol on the battery indicating Star Protection inside.
