The Makita 18V LXT® Lithium-Ion Cordless 2-Piece Combo Kit breaks new ground for drywall contractors. The XT255MB includes the 18V LXT® Brushless Drywall Screwdriver featuring the exclusive Push Drive™ Technology. With Push Drive™, the Screwdriver can be set in lock-on mode and the motor will start only when the fastener is engaged. This gives contractors a quieter work environment, and also saves battery power for longer run time -- enough to hang up to 40 sheets of drywall on a single charge! The combo kit includes the 18V LXT® Cut-Out Tool with a slim-body design and 30,000 RPM for fast cutting. The 18V LXT® 4.0Ah battery provides 35% more run time per charge than the 18V 3.0Ah battery (BL1830), with a category-leading charge time of only 40 minutes for less downtime and increased productivity. For added convenience, the batteries feature an on-board L.E.D. charge level indicator. It’s part of Makita’s expanding 18V Lithium-Ion series, the world’s largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. 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. 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.
