The system of modular elements comprises a plurality of disc elements (11, 12,...) with diamond outer rings (11a, 12a,...) for assembling on a single drive spindle with a spacing approximately equal to their thickness; mechanical fragmenting means (19, 20, 21, 22,...) being provided in the spaces between the disc elements to operate essentially by impact, in contrast to the abrasive action of the diamond outer ring of the said disc elements; which disc elements have different diameters forming a broken line that corresponds substantially to the outline of the profile or shaping to be produced on marble, stone or the like; the arrangement being such that the disc elements (11, 12,...) cut grooves by diamond abrasion and the mechanical fragmenting means (19, 20, 21, 22,...) shatter the parts projecting from the grooves with an action of fragmentation by impact and by brittle fracture.
