Makita’s HR1830F 11/16-inch Rotary Hammer (Accepts SDS-PLUS) is one of the most compact rotary hammers on the market. The HR1830F delivers more efficient hitting in a compact size for faster, more productive work. The compact size and high power-to-weight ratio makes the HR1830F ideal for overhead work and applications in close quarters. 4.2 AMP Motor and Two-Mode Operation The HR1830F features a Makita-built 4.2 AMP motor that delivers a no load speed of 0-1,500 RPM, with 0-5,000 BPM and 1.2 Joules of impact energy. Two-mode operation includes “Rotation Only” and “Hammering with Rotation” for multiple applications. Makita Motor Advantage Consistent with the rest of Makita’s rotary hammer line-up, the HR1830F 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. More Efficient Work Additional performance features include a torque limiting clutch engineered to prevent gear damage by automatically disengaging gears if the bit binds. The sequential impact timing feature delivers timed hammering during rotation to minimize overlapping bit impacts, resulting in up to 50% faster drilling. Comfort and Ease of Use Comfort and ease-of-use features include an ergonomic and well-balanced design with rubberized grip and a soft grip side handle. Additional features include a one-touch sliding chuck that allows for easy bit changes, a large trigger switch with recessed lock-on button for continuous use, and an L.E.D. light to illuminate the drilling surface. The extended life brushes are longer for less downtime and more work between service intervals. Versatile Design for a Range of Applications The HR1830F is one of the most compact rotary hammers on the market and is engineered for overhead work and applications in close quarters. It’s ideal for masons, remodelers, electricians, maintenance crews, and general contractors seeking a best-in-class 11/16-inch rotary hammer.
