  • Roller Cutter Bits - Air and Gas Drilling - Netwas Group Oil

    May 26, 2019  Roller cutter bits use a crushing action to remove rock from the cutting face and advance the drill bit. The weight or axial force that is applied to the drill bit is transferred to the tooth or teeth on the bit. These teeth are pointed (mill tooth bit) or rounded (insert tooth bit) and the force applied is sufficient to fail the rock in shear and tension and cause particles of the rock to ...
