The “DWC-DuraDrive power construction screwdriver” with magazine attachment works fast with ultimate driving performance and accuracy to save time. The D shape of the power screwdriver results in linear power transmission from the forearm to the tip of the screw so that pressing force is transmitted directly. In spite of its robust and durable construction, the DWC is lightweight and, thanks to its “EC motor” and “lithium-ion battery technology”, achieves optimum ergonomics, power and speed. With the start / stop function, the motor only runs while driving a screw – without operating the switch. The power screwdriver and magazine attachment form a compact unit for enhanced process security.
