The cordless model has high demolition performance equivalent to a mains-powered product. The h3641da is compact and lightweight thanks to significant weight reduction and the use of a brushless motor. It is compact and easy to use reducing operator fatigue during extended use. The breaker is equipped with a high-intensity white led light to provide illumination in dark areas. While the switch trigger is pressed the led automatically illuminates the tool tip. The led light automatically turns off 10 seconds after the switch trigger is released. The h3641da features low-vibration handles – the lvh system. The main body (cylinder crankcase) is connected to the upper handle by four cylindrical rubber bands (handle dampers). These rubber bands are rolled and compressed on an inclined surface to absorb vibration. This allows the h3641da to provide high vibration absorption while maintaining good performance. This demolition breaker utilizes a quick-attach chisel attachment method that requires no tools to attach the working tool. The angle of the working tool can also be adjusted in 30-degree increments and can be set to 12 positions. The h3641da model is equipped with control electronics that can adjust the impact force depending on the type of work. Four impact rates can be selected ranging from 1500 to 2880 bpm. The selected impact force can be maintained constant regardless of load.h3641da w2z - tool without battery and charger side handle 280 mm point carrying case.**
