XPH12Z 18V LXT Lithium-Ion Compact Brushless Cordless 1/2" Hammer Driver-Drill, Tool Only | Lithium-Ion, Compact, Tool Only

The brushless motor provides 530 in.lbs. of maximum torque. The efficient brushless motor is electronically managed to optimize battery energy use for up to 50% longer run time per charge. The brushless motor removes carbon brushes, allowing it to operate cooler and more efficiently for improved durability. The electronically-controlled brushless motor effectively uses energy to match torque and RPM to the changing demands of the application. A variable 2-speed design (0-500 & 0-2,000 RPM; 0-7,500 & 0-30,000 BPM) addresses a wide range of drilling, driving, and hammer applications. It features a compact and ergonomic design at only 7-1/8" long. It weighs only 4.2 lbs. with battery (battery not included) for reduced operator fatigue
