Abstract
A method of producing aggregated abrasive grains for cutting tools and the like, comprising sintering a mixture of abrasive material powders and metal or alloy powders together with 5 to 10% by weight of the metal powders of an adhesion-active agent, to obtain a cake which is subsequently crushed. The sintering takes place in a loose state so that the cake has a porous structure which by crushing forms aggregated abrasive grains which break along the voids.
