Claim:
1. An adapter device for a ceramic cutting machine having a tool holder and a hole formed in the tool holder, the adapter device comprising an adapter plug for the hole of the tool holder, the adapter plug comprising: a hollow cylindrical structure having a first end, a second end, and an upper cylindrical surface extending from the first end toward the second end, wherein the hollow cylindrical structure defines an inner hollow space; a stop for axially fixing the adapter plug in the hole of the tool holder, the stop being disposed at the first end and defining a circular sheet-like surface; and a longitudinal slot that leaves open the inner hollow space of the plug along the entire length of the hollow cylindrical structure, the longitudinal slot including a narrower segment in a part of the plug that is nearest the first end comprising the stop, and a wider segment in a part of the plug that is near the second end opposite the stop, wherein the wider segment of the longitudinal slot is laterally delimited by two straight segments, which are continuations of the upper cylindrical surface of the plug, wherein the adapter plug further comprises two lateral diametrically-opposed slots that leave open the inner hollow space of the adapter plug, wherein the diametrically-opposed slots extend from the first end and are respectively located 90° to the left and 90° to the right of the longitudinal slot, and have a smaller width than the width of the narrower segment of the longitudinal slot and a length equal to the length of the narrower segment of the longitudinal slot, and wherein both of the lateral slots and the narrower segment of the longitudinal slot permit an outer shape of the adapter plug to be adapted to a shape of the hole of the tool holder upon insertion, in the lateral slots and in the narrower segment of the longitudinal slot, of projections provided in the hole of the tool holder.
