Abstract
A small glass cutting wheel for producing a scribed predetermined breaking line, wherein the cutting wheel has a radial peripheral line which defines an outer periphery of the wheel and which lies in a main plane of the wheel and at least partially forms a cutting edge. The cutting edge includes cutting teeth which are circumferentially spaced from each other by intermediate tooth spaces and the height and/or circumferential extension of the cutting teeth exceeds a surface roughness. A small glass cutting wheel for manufacturing flat displays can be manufactured with an improved edge quality so that rejected glass plate pieces can be reduced. At least a part or preferably all intermediate tooth spaces include a cutting edge. Preferably, the cutting edges of the intermediate tooth space and the cutting edges of the teeth are arranged approximately in the same main plane of the small wheel.
