<p>The present invention relates to a diamond disc for cutting hard or abrasive products, such as stones, granite, sandstone, refractory products, concrete or similar products, which disc is composed of a sheet-metal support whose periphery comprises teeth separated by notches, and of diamond segments of a precise shape matching the curvature of the periphery of the support and whose thickness is greater than that of the sheet-metal of the support. This disc is characterised in that the leading edge of each tooth (2) is provided with a means (5) for protection against abrasion. <IMAGE></p> |
