An apparatus and a tool for chipping material are provided. The apparatus includes chipping tools arranged relative to one another inside a housing, whereby the chipping tools are constructed planiformly, and are arranged on carrier elements along a drum-shaped, disk-shaped, or ring-shaped chipping path. The chipping tools rotate relative to one another by rotating about an axis of rotation, and are each divided by a division line based on their thickness into a core area, which faces the carrier element, and a utilization area, which is positioned opposite of the chipping tools. The chipping tools have at least one bore, formed perpendicular to the division line, the bore extends across the utilization area and ends at the division line between the core area and the utilization area. In this way, an automatic indication of a critical state of attrition is accomplished, when from a static viewpoint damage to or destruction of the chipping tool as a result of mechanical stress during the operation of the apparatus can be expected. |
