Improved abrasive tools and apparatus and method for the manufacture of the improved abrasive tools and the like which includes apparatus and a method for the creation of a structurally viable matrix having a pattern of abrasive elements which can be shaped, cut and positioned for permanent disposition on a rigid tool body. The apparatus includes a release layer on a transversely magnetized base surface with magnetic protrusions to provide a mosaic-like surface. Magnetizable abrasive particles applied to the release layer orient themselves magnetically to form generally conic stacks which having a stack axis and a distal working portion. The stacks define a working surface which is then coated. Prior to solidification of the coating the cones may be shaped or raked magnetically. A braze paste is applied to encapsulate the cones and form a flexible support web between the cones. The entire matrix may then be removed from the release surface and cut, shaped, aligned and formed to any desired shape or configuration. The resulting configurations can emphasize cutting speed, finish and/or versatility at optimum cost.
