Abstract: A chuck which can be clamped into a spindle of a machine tool and which is for use with a cutting tool having a shaft with a circular cross section. The chuck includes a body provided with a central bore having an end region in which the surface of the central bore is conically shaped for receiving the shaft of the cutting tool. The body includes a shaft projecting toward its rear side. The shaft is configured to be clamped into the spindle of the machine tool and is provided with a further bore. A clamping screw is disposed in the further bore of the shaft and has a head which is accessible from the front side of the body. A pull rod is displaceably disposed in the central bore and has a threaded end extending into the end region of the central bore for connection to the shaft of the cutting tool. An attachment mechanism is provided for attaching the pull rod to the clamping screw so that displacement of the clamping screw in the further bore causes displacement of the pull rod in the central bore.
