Kelly Bar

Positioned at the top of the drill string, the Kelly Bar primarily serves to transmit torque and bear the total weight of the drill string. It is a critical component for ensuring the stable operation and precise penetration of drilling equipment in numerous fields, including oil drilling, construction foundation boring, and mining. Its efficient torque transmission enables the drill bit to power through various soil and rock formations, guaranteeing the smooth progression of drilling operations.
