ABSTRACT:
A bonded abrasive grit structure which may be attached to a tool surface and a method for making a grit structure and tool therefrom. The grit structure includes a plurality of peaks which have a grit particle at the apex and are substantially the same height such that the apexes collectively define a plane. A setting matrix of preferably tungsten carbide particulate matter of high melting point surrounds the grit particle. A resin binder is dispersed throughout the structure. The binder is drivable from the structure at a first temperature. The structure is brazeable to a tool surface by infiltration of a brazing material therethrough at a second higher temperature.
