Description

11/16" Rotary Hammer, accepts SDS-PLUS bits



Makita's HR1840 11/16-inch Rotary Hammer (accepts SDS-PLUS) is a compact and lightweight solution for concrete drilling. The HR1840 delivers more efficient hitting in a compact size for faster, more productive work. The compact size and high power-to-weight ratio makes the HR1840 ideal for overhead work and applications in close quarters.



The HR1840 features a Makita-built 4.3 AMP motor that delivers a no load speed of 0-2,100 RPM, with 0-4,800 BPM and 1.03 ft.lbs. of impact energy. Two-mode operation includes “Rotation Only" and “Hammering with Rotation" for multiple applications. Consistent with the rest of Makita's rotary hammer line-up, the HR1840 is engineered with the Makita Motor Advantage. This includes field core interlocking steel laminations, dual ball bearing armature, and more copper commutator bars. These features deliver the most efficient transfer of energy for more power and longer tool life. Additional performance features include a torque limiting clutch engineered to prevent gear damage by automatically disengaging gears if the bit binds.



Comfort and ease-of-use features include an Ergonomic "Pistol-shaped" handle with rubberized soft grip for increased comfort. Additional features include a one-touch sliding chuck that allows for easy bit changes, and a large trigger switch with recessed lock-on button for continuous use. The extended life brushes are longer for less downtime and more work between service intervals. The HR1840 is ideal for masons, remodelers, electricians, maintenance crews, and general contractors.
