Main features
High strength alloy steel: R780/R850/R950 grade steel is used to adapt to deep hole high load drilling.
Optimize the inner diameter design: ensure that the core retrieval tube passes smoothly and improve the efficiency of core retrieval.
High sealing: end face metal seal + precision thread, reduce the leakage of flushing fluid.
