Manually operable drilling tool with dual impacting function

摘要

A manually operable drilling tool (1) wiht dual impacting funtion has a housing (2) containing a first striking mechanism (16) for producing axial impacts to be transferred to a drilling or chiseling tool bit (7), clamped in a chuck (6) of the tool (1). Within the housing (2), a second striking mechanism (20) is arranged for producing axial impacts, the axial impacts of which have an impact energy and an impact frequency different from the impact energy and the impact frequency of the axial impacts produced by the first striking mechanism (16). The drilling or chiseling tool bit (7), clamped in the chuck (6), can be acted upon with axial impacts produced either by the first (16) or the second striking mechanism (20) or by both striking mechanisms together. The axial impact striking, mechanisms (16, 20) can also be switched off completely for use in wood or metal.
