Tornado water well bits are mainly used in drilling engineering of liquid circulation systems (such as water wells, coalbed methane, etc.). Tornado water well bits’ technology comes from the advanced oil roller bit manufacturer in the United States. Based on Shareate’s existing advantages in the design and manufacture of mining roller cone bits, Tornado is designed and manufactured in accordance with the standard of oil roller cone bits, which has a longer lifespan and higher drilling efficiency.
