Abstract
Abstract A toolholder for holding cutting tools is provided with a standard cone at its rear end for insertion into a machine tool. The front end consists of an axially projecting stud. Disc-shaped tool carriers are provided with a central bore and further with means for receiving and holding at least one cutting tool. By means of their bore, the tool carriers are arranged on the stud to which they are positively secured by clamping means, for example, by a bayonet coupling. The distance between the nose of the cutting tools and the rear surface of the tool carriers is at all carriers set to a uniform predetermined range, thereby avoiding any shifting of the zero-point when one tool carrier is exchanged for another one.
