The Hikoki DH12DDWHZ is a cordless rotary hammer designed for construction and repair tasks, especially in areas where power outlets are unavailable or difficult to reach. It features a brushless motor and operates on a 10.8V battery system, offering two modes for standard drilling and impact drilling. With an impact energy of 1.2 J and a no-load speed of up to 1080 rpm, this tool can handle concrete up to 18 mm, steel up to 13 mm, and wood up to 18 mm. Safety and comfort are integrated into the design through a Low Vibration Handle (LVH) and Reactive Force Control (RFC), which helps protect the user during sudden jams. The tool is compact, measuring 246 mm in length and weighing 2.03 kg with the battery attached, making it easy to maneuver in tight spaces. An integrated LED backlight ensures clear visibility in dark work areas, while the SDS-plus chuck allows for quick, tool-less bit changes. This set is ready for immediate use, as it includes two 4.0Ah BSL1240M batteries, a UC12SL charger, and a sturdy HSC2 carrying case. The variable speed control and automatic stop function allow for precise depth management, making it a practical choice for technicians and builders who need a portable yet powerful drilling solution.
