Makita, a pioneer in brushless motor technology and battery innovation, combines both in the 18-Volt X2 LXT (36-Volt) Lithium-Ion Brushless Cordless Right Angle Drill. It's powered by two 18-Volt LXT Lithium-Ion batteries for maximum performance, and has an electronically-controlled BL Brushless motor that matches torque and RPM to the changing demands of the application. Makita 18-Volt X2 means freedom from the cord, and the XAD03 will take on the most demanding applications like drilling up to 6-1/4 in. holes with hole saws and 4-5/8 in. holes with self-feed bits. Best of all, users can remain in 1 battery platform, using the same fast-charging 18-Volt batteries with the XAD03 as they use across the expansive Makita 18-Volt 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 RPM to 350 RPM and 0 RPM to 1,400 RPM. Under load, the Automatic Speed Change technology adjusts drill speed and torque during drilling for optimum performance.
