A rotary tool includes first and second tool bodies defining an axis and clamped together in the axial direction by a screw. The tool bodies include axially extending male and female parts that engage one another to transmit rotary force. Spaced radially outwardly of the male and female parts are two sets of radial guiding structures for guiding the tool bodies in the radial direction, so a radial play can exist between the male and female parts. |
