ABSTRACT:
A diamond coated elongate rotary cutting member and method of making the same. The cutting member includes an axially forward cutting surface, a flute and a fluted land. The cutting member comprises a substrate with hard grains bonded together with a metallic binder. The substrate has a first substrate region that presents an irregular surface so as to define the axially forward cutting surface and the fluted land. The first substrate region contains relatively large hard grains near the surface thereof that are larger in size than the hard grains in the interior of the substrate. A diamond coating is on the surface of the first substrate region. The substrate has a second substrate region that defines the flute.
