ABSTRACT:
It is the object of the present invention to drill a hole and, at the same time, transmitting an application force exactly to an undercutter for forming an undercut space in the cylindrical wall of the hole at a position near the hole bottom. An apparatus according to the present invention includes a rear circular member 1, a sleeve 10 supported in telescopic engagement with the rear member 1, an undercutter 5, and a front annular member 15 linking and movable with the undercutter 5. The sleeve 10 has an inner flange 13 forward from the rear member 1. An application force transmission mechanism 18 comprises a cam 20 supported by the rear member 1. The cam 20 has a pair of steps 21 and 22. The transmission mechanism 18 also comprises a first impact transmission rod 23 extending between the cam step 21 and sleeve flange 13, and a second impact transmission rod 24 extending between the step 22 and front member 15.
