Cutting tool, particularly for stone materials and the like

A tool for cutting stone materials, porcelaneous stoneware, glass and the like in a direction of cutting, the tool comprising:

• a disc-shaped support having a transverse thickness with respect to the direction of cutting and a circumferential cutting edge;
• and
• abrasive segments attached to the support and made from a mixture of abrasive material and binder, the segments being positioned in sequence along the cutting edge of the support and projecting from the support, the segments having a first and a second plurality of segments in which one or more segments of the first plurality alternate with one or more segments of the second plurality in sequences which are repeated along and attached by braze welding or laser welding to the cutting edge, the segments of the first and the second plurality have corresponding thicknesses which are greater than the thickness of the support and the segments of the first plurality are thicker than the segments of the second plurality, and the abrasive material from which the segments of the first plurality are formed has a smaller particle size than the abrasive material from which the segments of the second plurality are formed.

• a disc-shaped support having a transverse thickness with respect to the direction of cutting and a circumferential cutting edge;
• and
• abrasive segments attached to the support and made from a mixture of abrasive material including diamond powders and binder including powdered metals, the segments being positioned in sequence along the cutting edge of the support and projecting from the support, the segments having a first and a second plurality of segments in which one or more segments of the first plurality alternate with one or more segments of the second plurality in sequences which are repeated along and attached by braze welding or laser welding to the cutting edge, the segments of the first and the second plurality have corresponding thicknesses which are greater than the thickness of the support and the segments of the first plurality are thicker than the segments of the second plurality, the powdered metals of the segments of the first plurality have a different composition from that of the powdered metals of the segments of the second plurality, and the powdered metals of the segments of the first plurality have a smaller particle size from that of the powdered metals of the segments of the second plurality.
