PROBLEM TO BE SOLVED: To obtain the metal-bonded super-abrasive used for processing of a hard material such as cutting and drilling at a wet or dry processing, to obtain two or more kinds of super-abrasives with different brittleness without differentiating an amount of diamond or CBN and kinds of base bonds, and to obtain a super abrasive having a backing layer and using the soft base bond. SOLUTION: A problem of the super-abrasive is solved by using the metal-bonded super-abrasive including hexagonal boron nitride as a solid lubricant, wherein the content of the hexagonal boron nitride is 9 wt.% or less with respect to the base bond.
