Abstract
The tool holder of modular construction of driven tools for use on lathes consists at least of one base holder and various tool heads connectable interchangeably therewith. The base holder has a fixing shank, an attachment flange connected thereto, as well as a drive shaft rotatably mounted therein. Each tool head has at least one rotatable tool receptacle in a housing and a drivable shaft connected thereto. On the mutually facing ends of the drive shaft and the driven shaft there are provided coupling parts which can couple without relative rotation therebetween. The driven shaft is provided on the input side with a support pin freely projecting beyond the associated coupling part. The drive shaft is provided in the region of the attachment flange with a coaxial support bore, into which is received the support pin of the tool head.
