Web6 aug. 2002 · Laboratory drilling tests were conducted to obtain the penetration rate, bit weight and torque using milled-tooth bits with different tooth wear (T0, T4, T7). Drilling media used for the tests were soft to medium-hard rocks whose uniaxial compressive strength ranged from 14 to 118 MPa. WebAccording to the type of teeth, roller cone bits can be divided into milled teeth (steel teeth) roller cone bits and inserts (hard alloy tooth roller cone bits are installed on the roller cone; according to the number of roller cones, they can be divided into single rotary rock drill bit and tricone drill bit and assembled multi-cone bits.
