Makita is the innovation leader in Brushless motor technology, and the XT275PT Combo kit provides two BL Brushless motor tools that deliver longer run time, increased power and speed, and longer tool life. The XT275PT includes a Brushless hammer driver-drill with two speeds and 530 in.Lbs. Of torque, and a Brushless 3-speed impact driver with 1, 550 in.Lbs. Of torque for efficient fastening. Both tools are equipped with extreme protection technology (XPT), which is engineered to provide increased dust and water resistance in harsh job site conditions. The kit includes two 18V LXT 5.0Ah batteries, and both will reach a full charge in only 45 minutes on the efficient 18V LXT dual port charger, which charges two batteries at the same time for less downtime and increased productivity. For added convenience, the batteries feature an integrated L.E.D. Battery charge level indicator. 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.
