摘要： A tool holder, particularly a fast exchange chuck preferably for thread cutting, thread shaping and the like has a receptacle having one end receivable in a machine spindle, a machine tool receptacle and the like, and another opposite end provided with a head having a coaxial cylindrical head opening, a housing received and guided in the cylindrical head opening non-rotatably but displaceably in a longitudinal direction and provided with a coaxial cylindrical housing opening, a fast exchange insert insertable in the housing opening a torque-transmitting unit for transmitting torque between the head and the housing and including a head longitudinal groove provided in the head, a housing longitudinal groove provided in the housing, and at least one drive body partially received in each of the longitudinal grooves so as to transmit torque between the head and the housing and to roll during a relative displacement between said head and said housing. The at least one drive body is arranged between said head and said housing guidance-free with respect to its position in a longitudinal direction and is acted upon from outside inwardly with a pressing force, and an elastic clamping member applies the pressing force from outside inwardly to the drive member.
