INSERT FOR TOOL WEAR SURFACES AND METHOD OF MANUFACTURE ABSTRACT OF THE DISCLOSURE An abrasion resistant insert for use in the wear surfaces of a tool body includes a body portion having pockets in its exposed face and a solid matrix formed into each pocket by powder metallurgy. Each matrix includes at least one hard, abrasion resistant particle, for example, a diamond. A method of manufacturing an insert includes the steps of filling the pockets in the body portion with carbide matrix powder having a hard particle disposed therein, placing a binder on the matrix powder and heating the matrix powder and binder to a temperature sufficient to melt the binder so that the binder infiltrates the matrix powder to form the solid matrix.
