Zusammenfassung:An abrasive compact comprises an ultrahard polycrystalline composite material comprised of ultrahard abrasive particles having a multimodal size distribution and a binder phase. The ultrahard polycrystalline composite material defines a plurality of interstices, the binder phase being distributed in the interstices to form greater than an optimal threshold of binder pools per square micron.
