A tool holder is furnished for fastening a dentistry-type tool to be subjected to vibrations. A core is attached to a generator of vibrations and includes a housing for a tool. A locking assembly cap having a rear end is fitted onto a forward area of the core. A locking assembly sliding component is placed over a rear area of the core for contacting the rear end of the core with front end of the locking assembly cap. A compressive spring engages the core and the locking assembly sliding component for pushing the locking assembly sliding component in a forward direction.
