Circular saw blade, for cutting through wood or metal or rock or concrete or glass, has passage openings in the blade body in geometric pattern shapes according to working conditions to dissipate friction heat

摘要

The circular saw blade (1) has passage openings (2) through the blade body (2) in passage geometries (4), in a surface distribution of several and/or single openings at the edge zone (5). The passage geometries are in shapes (6) according to the working conditions, e.g. triangle, polygon, oval, circular, etc.
