The impacting tool has a tool holder and a locking part. The locking part can be driven to move between the bit holding position, where it is engaged with the tool bit inserted into the bit inserting hole so that pullout is restrained, and a bit holding released position where the engagement is released and pullout is allowed. The locking part and the tool holder can be integrated with each other while moving in the longitudinal direction of the tool bit, so that they can be driven to move between the bit anchored position where the locking part is set at the bit holding position and the engagement state with respect to the tool bit is maintained, and the bit last connection/disconnection allowed position where the locking part is set at the bit holding released position and releasing of the engagement with respect to the hammer bit is allowed. |
