PURPOSE: To obtain a grind stone plate that is hardly deformed or damaged by heat and is excellent in cutting and grinding performance, by molding a grind stone plate to include integrally an annular outer circumferential member of a certain thickness and an annular inner circumferential member of the same tickness as the first mentioned member or thinner that.

CONSTITUTION: The grind stone plate 1 comprises the annular outer circumferential member 2 of a thickness T and the annular inner circumferential member 3 of the thickness T, and the member 3 is fitted integrally in the inner circumference of the member 2. The grind stone plate 1' comprises the annular outer circumferential member 2 of the thickness T and the annular inner circumferential member 3' of the thickness (t) a little thinner than the thickness T, and the member 3' is integrally fitted in the inner circumference of the member 2. As hard grains, use is made of alumina grains, and silica grains such as silicon carbide grains and as a resin binder use is made of a thermoplastic resin such as phenolic resins. It is preferred to add a metal powder. The composition of the member 2 contains carbide grains, hard grains, a binder and a filler.
