A higher performance, lighter and thinner composite sawing disc for stony materials is made by assembling, preferably by bonding, a peripheral rim (2) provided with diamond segments (6) on a self-supporting, metallic honeycomb structure (3) strengthened at its center by a central ring (4). Excellent strength of the assembly is obtained by bonding annular discs (5) of thin plate to the lateral faces.
