Abstract
The present disclosure relates to an industrial device including a PCD element located in a recess of the industrial device. The PCD element and recess may contain an aligned mechanical lock. The device may also include a brazing material located along at least a portion of an interface between the PCD element and the recess. In a more specific embodiment, the industrial device may be an earth-boring drill bit, such as a fixed cutter drill bit, and the PCD element may be PCD cutter. In specific embodiments, the mechanical lock may include at least one ridge located at an end of the PCD element and in an end wall of the recess, at least one ridge located along a side of the PCD element and in a side wall of the recess, or at least an upper wall of the recess.
