Abstract
A drilling system is formed as a support structure to be mounted on a surface to be drilled, a beam supported by the support structure, a tool holder supported by the beam and having a locking orifice, and a drilling tool mounted on the tool holder by sliding connection in the direction parallel to the drilling axis. The drilling tool includes a bearing mandrel and an expandable ring closely fitting the bearing mandrel along a tapered contact surface for expanding the ring to ensure its locking in the locking orifice. Relative movement between the ring locked in the locking orifice and the bearing mandrel procures, by movement of the drilling tool relative to the tool holder via the slide connection, a movement of the bearing mandrel towards the surface to be drilled, through the locking orifice.
