The present invention includes an improved cutting element substrate for
cutting elements. The cutting element substrate includes non-planar,
non-linear interfaces with an abrasive layer of superhard material
affixed thereto often using a high pressure high temperature press
apparatus. The cutting element substrate includes a cant intersecting a
first and second interfacial surface. A plurality of truncated nodules
intersects the first surface and extends towards the second surface.
Arcuate segments protrude out of the second surface and are radially
positioned along the surface. The truncated nodules are ill-aligned with
the arcuate segments proximate the truncated nodules.
