Small glass cutting wheel

A small glass cutting wheel for producing a scribed predetermined breaking line, said small cutting wheel comprising:

• inclined lateral surfaces converging into a cutting edge defining an outer periphery of the small wheel, wherein the cutting edge lies in a main plane of the small wheel and has cutting teeth which are circumferentially spaced from each other by intermediate tooth spaces, each of the intermediate tooth spaces having a length in the circumferential direction from one of the cutting teeth to an adjacent one of the cutting teeth,
• said teeth having a height extending in the radial direction relative to said intermediate spaces, and said teeth having a dimension in the circumferential direction of at least 5 μm to 200 μm;
• wherein the radial height and/or circumferential dimension of the cutting teeth exceeds a surface roughness of the teeth;
• wherein the cutting edge of the intermediate tooth spaces and the cutting edge of the teeth collectively form the cutting edge for the cutting wheel and lie in said main plane of the wheel and are substantially co-linear;
• wherein the cutting edge does not extend laterally;
• wherein the cutting edge extends over the entire length of the intermediate tooth spaces in the circumferential direction;
• and
• wherein the small wheel does not include a cutting edge free groove between the cutting edge of the intermediate tooth spaces and a remainder of the cutting edge of the small wheel.
