Beschreibung
Zusammenfassung:	1. Machine tool, in particular an electric drilling machine comprising a control device (30) for the control of the drive of the machine tool, a clamping chuck (1), a signal transmitter (3, 4) connected to the clamping chuck (1) which is adjustable by means of a plate movable in axial direction (3) by means of the clamping jaws (2) of the clamping chuck (1), and a signal sensor in the housing of the machine tool, characterized in that the signal transmitter (3, 4) has ranges of different inductive or magnetic characteristics which are arranged annularly at the plate (3) and that on the shaft of the machine tool a signal sensor (7) which responds to inductive or magnetic changes is attached as actual value sensor for diameter and/or speed of the drill.
