Roller cutter drill bit having a texturized seal member
A rotary drill bit is described for use in drilling a well bore comprising: a bit body having a threaded pin at its upper end adapted to be detachably secured to a drill string for rotating the drill bit, and at least one depending leg at its lower end having a generally cylindrical bearing journal, constituting a first bearing member of the bit; a roller cutter of generally conical shape constituting a second bearing member of the bit. The roller cutter has a recess therein of generally circular section for receiving the bearing journal; bearing means for rotatably mounting the roller cutter on the bearing journal; and a lubrication system for providing lubricant to the bearing means; and the seal means comprising an annular seal member of elastomeric material compressed radially between the bearing members.
