Do more with less. The Makita 18-Volt LXT® Lithium-Ion Sub-Compact Brushless Cordless Impact Driver (model XDT15ZB, tool only, battery sold separately) is a fastening solution with significantly less weight. The 18V Sub-Compact Impact Driver is part of 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 Impact Driver. The XDT15ZB has an efficient brushless motor with two speed settings and dual L.E.D. lights illuminate the work area. The innovative Assist Mode (A-mode) helps eliminate "screw cam-out" and "cross threading" by driving at low speed until tightening begins, and is ideal for driving longer fasteners. At only 5-5/16 in. and 2.6 lbs. (with battery, sold separately) it is a fastening solution with superior comfort and handling. It’s part of Makita’s expanding 18V LXT® system, the world’s largest cordless tool system powered by 18V Lithium-Ion batteries. Makita 18V LXT® 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® and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside.
