The BX 3 was developed for cordless use and enables the driving of nails into concrete, solid brick and steel. The housing encases the motor, tensioning belt and springs in an unusually asymmetrical, optimally balanced form. The dimensions and weight are reduced to a minimum, making the device easy to use. In addition, the power tool features an ergonomic, anti-slip and vibration-absorbing handle, as well as a support foot with a scaffolding hook. An LED lamp shows the current charge status of the battery.
