ABSTRACT:
A spacer is provided for an essentially cylindrical tool on whose circumference arc-shaped blades are mounted with spacers between them by means of bolts extending in the axial direction through the spacers. The spacer is made of steel sheet and has tangs bent out of the plane of the sheet. The tangs determine the distance between neighboring blades and are disposed on the inside edge and outside edge of the spacer oriented in the circumferential direction of the tool and the spacer. The tangs situated side by side in the circumferential direction have spaces between them in order to make a simple adaption to different distances between neighboring blades possible while simultaneously improving the removal of heat.
