The electronically-controlled Brushless Motor efficiently uses energy to match torque and RPM to the changing demands of the application An efficient brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge Weighs only 2.8 Kg with BL1840 or higher battery (battery not included) for reduced operator fatigue Vibration absorbing handle moves independently of the motor and hammer mechanism for increased operator comfort Makita has created a new class in cordless with 18V LXT new compact tools. The Brushless DHR171 17mm SDS Plus Rotary Hammer is ideal for working in tight spaces and for overhead conditions.

The DHR171 has an efficient Makita Brushless Motor for up to 50% longer run time, increased power and speed, and longer tool life. It has 2-mode operation for “rotation only” or “hammering with rotation”, with 0-680 RPM, 0-4,800 IPM and 1.2 Joules of impact energy for fast and efficient drilling. The compact size and lower weight mean reduced fatigue for operators, especially for overhead applications.The Brushless Motor eliminates carbon brushes, enabling the BL Motor to run cooler and more efficiently for longer life Efficient Brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge Weighs only 2.8kg with BL1840 or higher battery (battery not included) for reduced operator fatigue

The cordless DHR171Z brushless rotary hammer from Makita is ideal for working in tight spaces and overhead thanks to its compact design. It has an efficient brushless motor for up to 50% longer run time, increased power and speed and longer tool life. It has a 2-mode operation for "rotation only" or "hammering with rotation", with 0-680 RPM, 0-4,800 IPM and 1.2 Joules of impact energy for fast and efficient drilling. The compact size and lower weight mean reduced fatigue for operators, especially for overhead applications.
