Abstract
A drilling tool includes a spindle, a housing at least partly housing the spindle, a feed gear drivingly connected to a motor and threaded around the spindle to feed the spindle in an axial direction of the spindle by mutual rotation between the feed gear and spindle during a drilling process, and a micro peck unit which includes an undulated cam profile and a follower arranged to bear against the cam profile, and which produces an oscillating movement of the feed gear and the spindle upon rotation of the feed gear during a drilling process. The micro peck unit further includes interposable rolling elements arranged to be re-positioned into a gap between two circular contact surfaces in order to separate the cam profile from the follower, such that no oscillating movement is produced by the unit when the interposable rolling elements are positioned inside the gap between the contact surfaces.
