ABSTRACT:
In order to improve a device (100) for a drilling machine (10) known per se for manual drilling with a casing (11), a grip (12), a tool chuck (13) and a tool (14), especially a drilling, reaming or counterboring tool, in such a way that manual drilling can be carried out with optimum conditions, it is proposed that the device comprises aworkpiece jigging device (15) with at least one contact face anda guide device (21) for the parallel guidance of the tool (14) and/or of the casing (11) when there is a displacement of the workpiece jigging device (15) relative to the casing (11), said displacement being coaxial with a machine axis and/or tool axis, anda suction-type extraction device (18) for conveying away and sucking away material chips, dusts and impurities from the area of the workpiece jigging device (15), or more precisely the machining point anda control device (27) for the control of the feed motion between the workpiece jigging device (15) and the casing (11), said control being active at least in sections along the path.
