The PSB 850-2 RA impact drill with its insulated aluminium housing was designed for DIYers with the highest standards. The powerful 850 watt motor with a two-speed gearbox and ergonomic construction meet every demand placed on it in terms of performance, durability and user-friendliness. First gear provides high torque, while second gear provides high speeds. Speed preselection and control, carried out using the setting wheel and trigger switch, allow you to optimise the tool for working with specific materials.
