The Makita DHR264 SDS Plus Rotary Hammer has a compact design with 40 bit angle settings. It has 3 modes of operation: Rotation, Hammering and Rotation Only. An ergonomic soft grip provides increased user comfort. It is powered by 2 x 18V Li-ion batteries (NOT Supplied) in series to supply energy to the powerful 36 Volt DC motor drive system. When different capacity batteries are used together, (for example 1 x 3.0Ah BL1830 and 1 x 4.0Ah BL1840, or fully charged BL1830 and 70% charged BL1830), the machine stops when the battery with less capacity gets empty.
