The network screwdriver VIHR SH-550/1 is a functional power tool with adjustable torque, designed for twisting and unscrewing screws, self-tapping screws, screws, dowels and other types of fasteners, as well as for drilling holes in various materials in everyday life and industry. It operates from the 220-230V power grid.

This screwdriver differs from the SH-550/2 model in that it has only one speed, less rotation speed (0-800 rpm) and maximum torque (20Nm). There is no backlight. At the same time, it is much cheaper and is ideal for those who rarely need a screwdriver.
