## HiKOKI DH3628DA 36V Cordless Rotary Hammer Drill Review The HiKOKI DH3628DA is a 36V Multi Volt cordless rotary hammer drill designed for professional use. Featuring an SDS Plus shank and a maximum drilling capacity of 28mm in concrete, this tool is built around three core principles: lightweight design, compact form factor, and low vibration. It is an excellent choice for professionals who need a reliable hammer drill for daily use on construction sites. ### Industry-First LED Vertical Support Function The standout feature of the DH3628DA is its industry-first LED Vertical Support Function (as of October 2022, among domestic Japanese power tool manufacturers). This innovative feature uses LED indicator lights to notify the user of the tool body's tilt angle, making it easier to confirm proper alignment before and after drilling. When working on walls or other surfaces that are perpendicular to the direction of gravity, the system detects tilt within a range of 5° vertically. However, it does not detect lateral tilt, and the LEDs do not illuminate while the trigger is pulled during active drilling. It measures orientation relative to gravity rather than relative to a sloped surface. Despite these limitations, this feature is incredibly useful for anchor installations and other applications where vertical accuracy is critical. ### Auto-Stop Function for Consistent Drilling Another noteworthy feature is the Auto-Stop Function, which memorizes the drilling time and automatically stops the motor after the memorized duration. This helps ensure consistent, uniform hole drilling when performing repetitive tasks under the same conditions, improving overall workmanship quality. ### Dust Collection System Compatibility The DH3628DA allows attachment and detachment of the optional dust collection system (Code No. 0037-9133) without removing the bit. In an era where jobsite dust management is increasingly important, this seamless integration with the dust collection system is a significant practical advantage that saves time and improves workflow. ### What's Included and What You Need to Know The tool comes with a side handle and depth gauge as standard accessories. This is the body-only model (NN), meaning the battery, charger, and carrying case are sold separately. If you already own HiKOKI Multi Volt batteries from other tools in the lineup, you can save money by purchasing just the body. For those new to the HiKOKI ecosystem, the additional cost of batteries and a charger should be factored into the total investment. Currently priced at ¥35,300 on Amazon.co.jp, the DH3628DA is a feature-rich professional-grade cordless rotary hammer drill. With its unique LED Vertical Support Function, Auto-Stop capability, and dust collection compatibility, it is a compelling choice for professionals seeking improved accuracy and efficiency in their drilling work.
