Abstract

A method for making an abrasive product comprising forming a structure (1) of a sinterable retaining matrix having at least one first region (2) containing a plurality of abrasive particles embedded therein and at least one second region (3) containing substantially less or no abrasive particles adjacent the first region (1), at least one of the regions substantially surrounding the other of the regions, sintering the structure to form a unitary structure, wherein the first and second regions are integrated along a border between the regions, and extracting at least the first region from the unitary structure to form an abrasive product.
