ABSTRACT:
A holder for rotary material removing tools which are used in machine tools has a housing with two coaxial sections which can be held end-to-end by a set of male coupling elements provided in one of the sections and extending into a groove of the other section. The other section carries a shaft or spindle which transmits torque to a material removing tool, and the other section is separable from the one section when the male coupling elements are extracted from the groove by discrete fluid-operated motors which can move the male coupling elements against the opposition of stressed coil springs. The tips of the male coupling elements bear against the other section in operative positions of the male coupling elements to thereby urge an end face of the other section against an adjacent end face of the one section.
