CFA Coupling Joints – Continuous Flight Auger Tooling

Application of CFA Coupling Joints:

Used to connect and extend continuous-flight-auger (CFA) drill strings, these coupling joints transmit high torque between auger sections during foundation piling work.

Features of CFA Coupling Joints

– Supplied as matched male and female coupling pairs.
– Five torque ratings available, from 30 kNm up to 250 kNm.
– Nominal sizes from 3″ (110 mm) up to 5″ (220 mm).

More Introduction of CFA Coupling Joints

Each coupling size is engineered around a matched allowable torque rating, so the joint does not become the weak point in the drill string when boring through dense or mixed ground conditions.
