description The utility model discloses a drilling tool and a clamp thereof. The drilling tool comprises a clamp body and a cutter arranged below the clamp body, a bolt is formed at the upper end of the clamp body, and a mounting hole is formed below the bolt. A clamping hole is formed in the mounting hole, oil cavities are correspondingly formed in the two sides of the mounting hole, and an expansion wall is correspondingly arranged between the two oil cavities in one side. A telescopic protrusion is arranged at the upper end of the cutter. According to the drilling tool and the clamp thereof, through the arranged expansion wall, the cutter can obtain larger space and clamping force in the mounting and using process; through the arranged clamping hole and the telescopic protrusion, in the working process of the cutter, the conditions of mounting errors of the cutter and falling of the cutter can not happen. The drilling tool and the clamp thereof are simple and reasonable in structure, convenient to use, safe and reliab
