The makita 18V LXT lithium-ion brushless 3-piece combo kit (model XT328M) gives you three efficient brushless tools for drilling, driving, fastening, and demolition. You also get the category's fastest-charging 4.0ah batteries and the expansive breadth-of-line of the makita 18V LXT battery platform, so your batteries will power the expanding range of makita tools and accessories. The XT328M includes a variable speed ½" hammer driver-drill with two speed settings, and a variable speed impact driver with a full 1, 500 inch-pounds of max torque. The recipro saw has a refined crank mechanism design that minimizes blade deflection and reduces vibration for faster, more efficient cutting. For added convenience, the 18V LXT 4.0ah battery has an on-board L.E.D. Charge-level indicator and reaches a full charge in only 40 minutes. It's part of makita's expanding 18V lithium-ion series, the world's largest cordless tool line-up powered by 18V lithium-ion slide-style batteries. Makita 18V lithium-ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger.
