We are offering electric torque wrench. An electric torque wrench is a planetary torque multiplier or a "gearbox" mated to an electric motor. At the end of the "gearbox" is a reaction device that is used to absorb the torque. This allows the operator of the tool to use the electric torque wrench with very little effort. These tools are primarily used anywhere accurate torque is required on a nut and bolt, or where a stubborn nut needs to be removed.
