1. A clamping system (1) for rotating tool (70) with a shaft (74), comprising:

  • a. a base element (10), comprising a chuck for turning, milling or other rotating machines and similar with a receiving bore hole (12);

    b. a collet (30) with a tool bore hole (32) for the rotating tool (70), wherein the collet (30) is removably arranged in the receiving bore hole (12) of the base element (10) and is preloadable with friction locking relative to the base element (10) for providing rotational fixation wherein a clamping nut (50) axially forces the collet (30) into the receiving bore hole (12) of the base element (10); and

    c. a first rotation safety which blocks a rotation of the collet (30) relative to the base element (10) wherein the first rotation safety is provided by at least two catch elements (40) provided on the collet (30) in a distance to a longitudinal axis (R), wherein the catch elements engage recesses (20) on the base element (10) that are shaped complementary to the catch elements (40) in order to form a form locking connection and wherein the catch elements (40) are advantageously configured as a plug in components in form of engagement lugs that engage recesses (20) that are open in the radially inward direction so that a radial inside of the engagement lugs is configured for contacting the shaft (74) of the rotating tool (70).
