A metal bond super abrasive grain grinding wheel is provided to maintain acuity of particle while grinding materials difficult to grinding, such as cemented carbide, ceramic, and cermet. A metal bond super abrasive grain grinding wheel is comprised of a diamond particle(1), a secondary particle(2), a metal binder(4), a glass particle(3). The concentration of the diamond particle as 20%~40%(Vol). GC and graphite particle are contained as the secondary particle with 10%~30%(Vol). The metal binder contains the metal amount of 2 kinds selected from the Cu, Fe, Ni, W, Co, Sn, Ag from 20%~50%(Vol). SiO2, AI2O3, SiC, B2O3, RO, R2O are contained as the glass particle from 10%~30%(Vol).
