  • Reamers and methods for directional drilling
    Patent number: 8281876
    Abstract: A reamer includes a mandrel defining a mandrel axis and arms extending radially from the mandrel. Each arm has a proximal end and a distal end. The reamer includes a cutting head disposed on the distal end of each arm and cutting teeth disposed on each cutting head. The cutting heads are arcuately spaced about the central mandrel to allow the movement of debris axially along the central mandrel and at least one of the arms defines a square cross-sectional shape.
