PROBLEM TO BE SOLVED: To provide a cutting grinding wheel with excellent spontaneous effect having a high cutting force with high precision, without causing deterioration in cutting performance by clogging even in a long-time grinding. SOLUTION: This cutting grinding wheel with a binder 2 of metallic material comprises at least one abrasive grain 1 selected from diamond, CBN, silicon carbide and aluminum oxide, the binder 2 consisting of at least binder selected from metals of cobalt, nickel and copper, or an alloy of at least one of cobalt, nickel and copper with at least one of iron, silver, tin, zinc and tungsten, and amorphous carbon 3 that is an auxiliary material. The abrasive grain 1 and the amorphous carbon 3 are distributed in island shape in the binder 2.
