Abstract

A bonded abrasive tool, having a structure permeable to fluid flow, comprises sintered agglomerates of a plurality of abrasive grains and a binding material, the binding material being characterized by a melting temperature between 500 and 1400~C, and the sintered agglomerates having loose packing density of <= 1.6g/cc and three-dimensional shape; a bond material; and about 35-80 volume % total porosity, including at least 30 volume % interconnected porosity. Methods for making the sintered agglomerates e.g., Fig. 1, and abrasive tools containing the sintered agglomerates are described.
