A method of producing tool insert which includes the steps of: (a) providing a substrate (10) having a plurality of recesses (12) therein; (b) placing in each recess (12) an ultra-hard abrasive body (14) of substantially the same size and shape as the recess; (c) brazing the bodies to the substrate (10); and (d) cutting the substrate (10) through the recesses (12) containing the bodies to produce at least one tool insert comprising a section of the substrate (10) to which is bonded at least one ultra-hard abrasive body (14) at an edge thereof.
