Powerful, long-lasting, and efficient motor allows for compact and low weight design with exceptional run time. Universal, standard quick-release chuck accepts 1/4” impact-rated bit holders and bits. Optimized design with removable, reversible belt clip and generous magnetic bit storage. The TID 18 cordless impact screwdriver offers extremely strong performance and ensures that work is tailored to the material with three speed settings. The clever T-mode detects the transition between sheet metal and wood and automatically adapts the speed. With a long trigger pull you can incrementally adjust the speed to reduce the risk of overdriving screws and fasteners.
