Kelly Bars
Kelly bars are crucial components connecting the power head and drill bit of a rotary drilling rig, responsible for precisely transmitting enormous torque and pressure to the bottom of the hole. We offer a full range of friction type and interlocking/lock type Kelly bars suitable for various geological conditions, from clay and sand to hard rock formations.
Want to drill ultra-deep holes (over 60 meters)? Choose a friction-type Kelly Bar for smooth extension and retraction, doubling efficiency.
Want to drill through hard rock or boulder layers? Choose a mechanical lock-type Kelly Bar with pressurization function, penetrating rock as easily as drilling soil.
Features and advantages of kelly bar:
- Superior steel, stronger torsional resistance: Reject inferior tubing! Crafted from high-strength alloy seamless steel tubes (St52 equivalent), the drill rod remains rock-solid even under extremely high torque.
- Wear-Resistant Technology: Hard facing welding on both inner and outer keys ensures precise fit and special heat treatment between drill rod sections, significantly extending service life.
