ABSTRACT:
A method for fabricating cutting pieces or inserts wherein a billet (12) is formed by hot pressing of a powder metal, nonmetal, or combination thereof. After the billet has been formed, a series of holes (14) are drilled in a predetermined pattern in the billet (12). Finally, an insert (16) is cut around each of the holes (14) while simultaneously cutting the periphery of the next adjacent insert (16). The holes (14) and inserts (16) are preferably cut by directing a laser beam at the billet (12).
