| description | An abrasive compact cutting element includes an axisymmetric superhard abrasive element having a proximal cutting end, an inwardly tapered distal attachment end, and an outer surface; and an axisymmetric cemented carbide support element configured to receive the abrasive element tapered attachment end. The outer surface of the proximal cutting end of the abrasive element is spaced-apart from the outer surface of the carbide support element. The abrasive compact cutting element can be manufactured by forming an axisymmetric annular cemented carbide support element having an upper proximal end, a lower inwardly tapered distal end, and an outer surface. Abrasive particles are disposed in the annular cemented carbide support element. HP/HT processing forms an polycrystalline abrasive particle compact having a proximal cutting end and a tapered distal attachment end which compact is disposed within the annular cemented carbide support element. Cemented carbide is removed from the annular cemented carbide support element about its outer surface to reveal the polycrystalline abrasive compact proximal cutting end which has an outer surface that is spaced-apart from the outer surface of the carbide support element. |
