ABSTRACT:
In a device for clamping a circular saw blade, the saw blade is firmly clamped between two flanged rings and thereby connected to these so as to form an exchangeable tool unit which is pushed onto the free end of a saw shaft for rotation with the saw shaft and slidable displacement. Compression springs or the like are arranged between the tool unit and a stop face at the free end of the saw shaft to act upon one of the flanged rings and move the tool unit a short distance away from the stop face. A rotatingly mounted thrust plate which can be pressed centrically against the other flanged ring causes the tool unit to firmly engage on the stop face of the saw shaft.
