  • Reamers for earth-boring applications having increased stability and related methods
    Patent number: 10597947
    Abstract: Reamer for earth-boring applications may include a body having a longitudinal axis and a blade carried by the body. The blade may include at least one cutting element located at a first radial distance from the longitudinal axis and a gage pad located at a second, smaller radial distance from the longitudinal axis. Methods of enlarging pilot holes in earth formations utilizing reamers may involve removing earth material from a sidewall of the pilot hole utilizing at least one cutting element located at a first radial distance from a longitudinal axis of a body of the reamer on a blade of a reamer. The reamer may be stabilized by placing a gage pad located on the blade in sliding contact with a portion of the sidewall of the pilot hole, the gage pad located at a second, smaller radial distance from the longitudinal axis.
