Abstract
The metal bonded diamond wheel of the invention has a sintered body of a mixture of a diamond powder and a bonding metal powder. The particles of the bonding metal powder or, preferably, particles of both of the diamond powder and the bonding metal powder are provided, prior to powder metallurgical sintering, with a coating layer of iron, cobalt or nickel, in a thickness of 0.5 to 15 .mu.m. When sintered under adequate conditions, the sintered body has pores in a porosity of 10 to 25% and exhibits greatly improved grinding performance relative to the durability in grinding works and sharpness of grinding with a decreased resistance of grinding.
