A cutter block for attachment to a rotatable drive shaft is composed of two semi-circular elements which are connected to one another and together form a torus. Each element has a cavity therein which is defined on the radially inner side of the element by a flexible membrane. To attach the block to the shaft, the block is slid over the shaft and the cavities are then pressurized to distort the flexible membrane. The cavities are connected to one another in gas-tight manner by a passage sealed by an O-joint.
