Compact 2‑Mode Rotary Hammer | Lightweight & Powerful | Ideal for Concrete & Masonry
The Makita HR1840 is a compact SDS‑Plus rotary hammer drill offering two operating modes: rotation only and hammer drilling. Powered by a 470 W motor, it delivers 1.4 J of impact energy and produces up to 4,800 bpm, with speeds up to 2,100 rpm—perfect for overhead, fine finish, and tight‑space drilling tasks. It includes a torque‑limiting clutch, variable speed trigger, and a reversible sliding chuck for fast, efficient bit changes.
The HR1840 is available in both 240 V (standard mains) and 110 V (site-safe) versions, making it suitable for domestic, trade, and construction site environments.
