The Makita DHR280 LXT Brushless Rotary Hammer is powered by 2 x 18V Li-ion batteries in series (not supplied), to supply energy to the powerful 36V DC motor drive system.
Its powerful brushless motor has a 'soft no load' function which automatically reduces the motor speed during idling to suppress the vibration of the machine body. The variable speed is controlled by a trigger and it offers 3 operating modes: rotary only, rotary hammer and hammer only.
Anti-vibration technology decreases fatigue during use. There is also an electric brake for added safety and an LED job light.
Comes as a Bare Unit, No Battery or Charger.
