Abstract (en)
[origin: WO0145908A1] The invention relates to a schlag supported hand drill having a tool holder (10) which can be powered by a motor (14) having a roataion frequency and a Schlag frequency. The rotataional fequency and the Schlag frequency are matched with each other in such a way that at a certain rotational frequency ein bei einem Schlag aufgespannter Winkelbereich (w) between a groove (18) and an adjacent groove (20) in the circumferential direction with subsequent Schlägen and the same groove angle distances alpha abarbeitbar ist wie bei einer kleineren VErgleichsdrehfrequenz.
