The invention discloses a drilling tool screw thread connector cleaning tool. The drilling tool screw thread connector cleaning tool comprises a male thread spraying cleaning head, a female thread spraying cleaning head and a control handle. The control handle comprises a barrel body and an air inlet control switch. The two ends of the barrel body are connected with the male thread spraying cleaning head and the female thread spraying cleaning head correspondingly. The barrel body is provided with an air inlet connector used for being connected with an air pump pipeline. The air inlet control switch controls airflow to be sprayed from the male thread spraying cleaning head or the female thread spraying cleaning head. The drilling tool screw thread connector cleaning tool is light, convenient and easy to operate; drilling tool screw threads are cleaned through the high-speed airflow, the labor intensity is low, and the cleaning speed is high; in addition, the risk that the screw threads are damaged by manual operation can be avoided, and both the male thread and the female thread can be cleaned; and meanwhile, the male thread spraying cleaning head can be replaced according to the size of the male thread, so that the efficient cleaning effect of the cleaning tool is ensured.
