Claim 0:
1. Handheld setting tool for driving a nail or bolt into a substrate, comprising:
a drive, driving an actuator (11) which serves to drive the nail or bolt into the substrate;
a decoupling device which at least partially decouples a first movement process of a first moving part or piston (111) in the actuator (11), driven by the drive, from a second movement process of a second moving part or piston (112) in the actuator (11) for driving the nail or bolt,
the drive being a first electrodynamic drive or a second electrodynamic drive,
wherein the first electrodynamic drive comprises: a first excitation coil; a soft magnetic frame, and a squirrel cage rotor or squirrel cage winding movably mounted along an axis formed in a movable element that effects the movement process of the first moving part or piston (111) in the actuator (11), the soft magnetic frame having a saturation flux density of at least 1.0 T and/or an effective specific electrical conductivity of at most 10{circumflex over ( )}6 S/m,
wherein the second electromagnetic drive comprises: at least a first coil (711) and a second coil (721), the first coil (711) being formed on and/or in a flux concentrator (710) and the second coil (721) being a moving coil formed in or on a movable element (720) which effects the movement process of the first moving part or piston (111) in the actuator (11).
