Patent ID: 7909121

Claim:
A polycrystalline ultra-hard compact construction comprising: a polycrystalline ultra-hard compact having a polycrystalline ultra-hard body that is joined directly to a substrate, wherein the ultra-hard body comprises a material microstructure of bonded together ultra-hard particles; and a support member that is attached to a surface of the compact by a braze material, the support member comprising: a first section that extends axially along and that is attached to a wall surface of the compact; a second section that extends radially along and that is attached to a back side surface of the substrate of the compact; and a third section that extends radially along and that is attached to a front side surface of the ultra-hard body of the compact; wherein the support member comprises one or more materials having a greater thermal expansion property than the compact such that the compact is in a state of axial compression within the support member.
