  3. Because of its intergral construction, it can not fly out and hurt you.
  4. The contact between Kelly and roller is rolling contact, so friction is lower, and weight on bit is accurate.

  6. Through the rotation of four rolls, the friction between rolls and kelly pipes is reduced to extend service life.
  7. Two transmission styles (square and pinconnect) are available.
