ABSTRACT:
Polycrystalline ultra-hard compact constructions comprise a polycrystalline ultra-hard compact having a polycrystalline ultra-hard body attached to a substrate. A support member is attached to the compact by a braze material. The support member can have a one-piece construction including one or more support sections. The support member has a first section extending axially along a wall surface of the compact, and extending circumferentially along a portion of the compact. The support member can include a second section extending radially along a backside surface of the compact, and/or a third section extending radially along a front side surface of the compact. In one embodiment, the support member includes a second and/or third section and the compact disposed therein is in an axially compressed state. The support member is interposed between the compact and an end-use device.
