<p>A tool assembly includes a support body (1A), a clamping device, and a tool holder (5) clamped in a groove (1B) of the support body. A stopper block (2) is disposed in the groove and abuts against the tool holder for positioning the tool holder along an axis. The stopper block is held in place by a wedge-type stopper clamp (3) which applies a clamping force to the stopper block in a direction transversely of the axis. A wedge-type holder clamp (4) is provided for applying a clamping force to the tool holder in a direction transversely of the axis. The stopper clamp is secured to the support body by a single fastening bolt (6), and the holder clamp is attached to the support body by a single fastening bolt (7). Each of the fastening bolts is provided with a part that forcefully pushes the respective clamp away from the support body in response to loosening of the fastening bolt. The arrangement is such that the tool holder can be inserted and removed without completely removing the holder clamp or its fastening bolt.
