Abstract:
A hand-held power tool has a torque-limiting unit with which a maximum torque transferred from a motor output shaft to a tool driver is adjustable by an operator. The torque-limiting unit has a spring system with spring elements having substantially similar characteristics (such as length, compression forces, etc.) and yet generating different spring forces.
