Makita HR4003C Rotary Demolition Hammer – 40 mm SDS‑Max


Powerful 2‑Mode Rotary Hammer | 1,100 W Motor | Rotation + Hammering Modes | Available in 110 V & 240 V


The Makita HR4003C is a high-performance SDS‑Max rotary demolition hammer designed for durable use in construction and refurbishment. With its robust 1,100 W motor, this model delivers up to 8.3 J impact energy for drilling and chiselling concrete and masonry—up to 40 mm diameter, or 105 mm core drilling.


It features two selectable power‑on switches in hammer mode, enabling both continuous chipping and intermittent use depending on the task. The two‑mode operation supports both rotary‑drill and hammer‑only settings, while variable speed, soft start, torque limiter, and constant speed control ensure precision and safety under load.


Available in both 110 V (site‑safe) and 240 V mains versions to suit your working environment.
