Makita, a pioneer in Brushless motor technology and battery innovation, combines both in the 18V X2 LXT (36V) Lithium-Ion Brushless cordless ½” right angle drill. It's powered by two 18V LXT Lithium-Ion batteries (batteries sold separately) for maximum performance, and has an electronically-controlled BL Brushless motor that matches torque and RPM to the changing demands of the application. Makita 18V X2 means freedom from the cord, and the Xad03 will take on the most demanding applications like drilling up to 6-1/4” holes with hole saws and 4-5/8” holes with self-feed bits. Best of all, users can remain in one battery platform, using the same fast-charging 18V batteries with the Xad03 as they use across the expansive Makita 18V LXT cordless system. The Xad03 has a long list of features for drilling with superior speed and efficiency. The Makita BL Brushless motor combined with X2 LXT technology delivers no-load drilling speeds of 0-350 RPM and 0-1, 400 RPM. Under load, the automatic speed Change technology adjusts drill speed and torque during drilling for optimum performance. Added features include an Electric brake for maximum productivity, and a built-in clutch that reduces gear damage by disengaging gears if the bit binds (low speed only). it’s powered by two 18V LXT batteries for maximum power, speed and run time without the hassles of a cord. When using two 18V 5.0Ah batteries and a self-feed bit (batteries and bit sold separately), the Xad03 will deliver up to 160 2-9/16" holes per charge in 2x SPF. It’S part of Makita’s expanding 18V Lithium-Ion system, the world’s largest cordless tool system 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. 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.
