The invention relates to a small cutting wheel for producing a scribed/scored predetermined breaking line, wherein the cutting wheel has a radial peripheral line defining an outer periphery of the wheel which at least partially presents a cutting edge having cutting teeth which form a rough tooth system and which are circumferentially spaced from each other by intermediate tooth spaces. A cutting wheel shall be provided by which particularly flat displays but also other glass bodies can be produced with an improved quality of the separation planes and breaking edges and with minimum rejects also in different cases of application. For this purpose it is proposed that the cutting teeth of the rough tooth system include at least over a part of the perimeter of the small wheel a non-uniform arrangement in which the length Z of the cutting teeth and/or the length S of the intermediate tooth spaces varies at least between some adjacent teeth and/or intermediate tooth spaces or between all teeth and/or intermediate tooth spaces.
A small cutting wheel for producing a scribed predetermined breaking line, said small cutting wheel comprising a radial peripheral line defining an outer periphery of the small wheel, which peripheral line at least partially presents a cutting edge with cutting teeth which form a rough tooth system and which are circumferentially spaced from each other by intermediate tooth spaces, wherein the cutting teeth of the rough tooth system are in a non-uniform arrangement over at least a part of the circumference of the small wheel, wherein the length Z of the cutting teeth and/or the length S of the intermediate tooth spaces vary at least between some of the adjacent teeth and/or intermediate tooth spaces or between all teeth of the tooth arrangement.
