The Einhell TP-CI 18 Li Brushless-solo impact driver is a high-power member of the Power X-Change family. It is compatible with all the batteries and chargers from the line. The brushless motor also delivers more power and runs longer than a conventional motor. Tightening large and long screws is an effortless undertaking with the impact driver. It comes with a ¼" (6.35 mm) hexagon tool chuck. The finely adjustable electronic speed control can be adjusted to your requirements. Thanks to its short, light-weight design it reduces body stress and fatigue, and the ergonomic Softgrip surfaces provide a firm hold. This product comes without a battery and charger which are available separately.
