Abstract: An example rolling cutter assembly includes a rolling cutter disposable within a cutter pocket defined in a drill bit, the cutter pocket including a receiving end, a bottom end, and a sidewall extending between the receiving and bottom ends. The rolling cutter provides a substrate having a first end with a diamond table disposed thereon and a second end arrangeable within the cutter pocket at or near the bottom end. A bearing element is disposable within the cutter pocket at the bottom end and engageable with the second end of the rolling cutter as the rolling cutter rotates about a central axis.

Abstract: Catalyst extraction from polycrystalline diamond table may be achieved by treating with a halogen (in the gas phase or dissolved in a nonpolar organic solvent) to convert the catalyzing material to a salt. Then, polar organic solvents may optionally be used to leach the salt from the polycrystalline diamond table. The polycrystalline diamond (with the salt of the catalyzing material present or at least partially leached therefrom) may be brazed to a hard composite substrate to produce a cutter suitable for use in a matrix drill bit.
