Introduction to thread button bits

Threaded drill bits are also knowm as button bits which conmect with threaded dri11 rods by threads to transfer impactpower and rotation torque for breaking rocks, The threaded dri11 bits, working with hydraulic dri11 rigs and hydraulic jumboshave main threads of R22, R25,R28, R32, TR35, T38, T45, T51, ST58, ST68, EL60, EL68 and T60.

Materials and craftsmanship
