Beschreibung
Zusammenfassung:	A machine and a method for drilling a hole or setting a screw is provided, wherein the machine comprises a motor having a shaft and one or more magnetic coils, providing electric current to the one or more magnetic coils to rotationally drive the shaft, and switching the electric current at a commutation frequency to define a rotational speed of the shaft. A signal may be generated when a force towards the machine applied to the shaft increases and/or a torque applied to the shaft increases and the rotational speed of the motor may be increased to a first rotational speed when the signal is received. The rotational speed may be at least 6,800 RPM and at most 8,500 RPM.
