They apply three kinds of force to the task of advancing a tri-cone drill bit into rock. Bit-loading force up to 150,000 pounds-force (670,000 N) combines with up to 25,000-foot-pound-force (34,000 N⋅m) of torque and large volumes of compressed air flowing at nearly 3,850 cubic feet (109 m 3 ) per minute create the tubes or "blast holes."
