    摘要: In one aspect of the invention, a degradation assembly has a holder attached to a driving mechanism and comprising a longitudinal central bore. The bore has an opening at a distal end from the driving mechanism. The pick has a body intermediate a shank and an impact tip, the shank being disposed in the central bore of the holder and the body extending from the opening of the bore. The impact tip has a diamond surface. The degradation assembly also has a lubrication mechanism adapted to apply lubrication to the shank.

    摘要: In one aspect of the invention, a degradation assembly comprises a holder. The holder is attached to a driving mechanism and comprises a longitudinal central bore. A pick comprises a body intermediate a shank and an impact tip, and the shank is disposed in the central bore of the holder. The impact tip comprises an impact surface diamond or cubic boron nitride. At least one rolling element is disposed intermediate an inner bore surface and the shank, and is adapted for low-friction rotation with respect to both the inner bore surface and the shank.
