Abstract

A cutter for a drill bit includes a substrate defining a hole at least partially through the substrate. A diamond table including a protrusion is received within the hole such that a gap is defined between the protrusion and the substrate ranging between 0.001 and 0.010 inches when the substrate and diamond table are at standard temperature and pressure (STP). A braze alloy couples the diamond table to the substrate at an interface between the diamond table and the substrate. At least a portion of the braze alloy is disposed in the gap in compression between the protrusion on the diamond and the hole in the substrate.
