- 摘要：
- A reamer bit for use in earth boring operations comprising a body, four cutter mounts, rolling cutters on each mount, and cutting elements disposed on each cutter arranged so adjacent cutting swaths formed by the bit are created by cutting elements on cones of oppositely disposed cutter mounts. The swaths are generally curvilinear, wherein the outermost swaths are formed by cutting element rows on the outer portion of the cutters. The reamer bit can further comprise a pilot bit.
