Abstract

PURPOSE: To prevent a blade from coming off due to impacts by adhering the blade on a surface including a group of outer through-holes arranged in an outer peripheral edge portion of a metallic disc and on the wall of each of the through- holes.
CONSTITUTION: Outer through-hole group 2 and inner through-hole group 3 are formed in two arcuate rows at an outer peripheral portion of a metallic disc 1. On the surface of the outer peripheral portion of the metal disc 1 including the outer through-hole unit 2 and inside of each outer through-hole 4, a mixture of a resin such as synehetic resin as a binder and various abrasive powder is applied and then heated under pressure thereby bonding a blade 5 to the metal disc 1. Therefore, since the blade 1 is bonded to the surface including the outer through-hole unit 2 and the walls of the through-holes 4 and the pressure-hardened mixture on the upper and lower faces are united into an integral body, thus being strong against impacts. At the same time, as the inner through-hole unit 3 is left uncovered as they are, a great cooling effect can be obtained.
