摘要 |
A reamer bit for use in earth boring operations comprising a body, cutter mounts having rolling cutters on the bit body, and stabilizers pads on the body placed between adjacent cutter mounts. The reamer may further include a pilot bit on a drill pipe extending downward from the reamer body. The reamer bit outer periphery with its stabilizers and bit body has a radial profile approximating a circle thereby reducing dynamic perturbations during drilling operations.
