Infiltrated diamond bodies for use in gripping drill rods and other tubulars. One example of such an infiltrated diamond body is a cast diamond roller having a plurality of pads that are separated by channels. Another example of such an infiltrated diamond body is a cast wrench jaw having at least one raised jaw pad.

Diamond bodies and tools for gripping drill rods

A drill bit comprises a first and a second body received within the first body. Each of the first body and second body has a respective crown, each crown having an inner and an outer operative circumference. The outer operative circumference of the second body and the inner operative circumference of the first body can define a first volume that can receive a tubular core sample. The second body can define a break surface that breaks the tubular core sample into core pieces. The drill bit can be employed in a borehole with a reverse circulation system that pumps fluid around an outer surface of the bit, and returning fluid can carry the core pieces out of the borehole.
