  • Polycrystalline diamond cutter with improved abrasion and impact resistance and method of making the same
    Patent number: 8789627
    Abstract: Disclosed are a high impact/high abrasion cutter and a method for manufacture. The high impact/high abrasion cutter includes a plurality of preformed polycrystalline abrasive bodies sintered under high temperature/high pressure conditions to form an abrasive cutting table. The impact and abrasion resistance of a cutter can simultaneously be improved through forming a cutting table from larger preformed polycrystalline sintered particles formed from finer grain particles. Such a cutter can be manufactured through the steps of preforming the polycrystalline abrasive bodies, forming a mixture of said polycrystalline abrasive bodies and sintering said mixture under high temperature/high pressure conditions.
