Abstract

A drilling and/or chiseling device has a drive spindle (19) for a drilling and/or chiseling tool with two ring gears (17, 18) of different sizes, a countershaft (1) with a drive pinion (15), a wobble drive (7) for a striking mechanism, mounted on the countershaft (1), and a switching sleeve (9), mounted on the countershaft (1) so that it can be shifted axially by a switching element (20). The switching element displaces the switching sleeve (9) into four different modes of operation of the drilling and/or chiseling device.
