According to the technical scheme, the cutting tooth cylindrical drill for processing the complex rock strata comprises a cylindrical drill body, one end of the cylindrical drill body is fixedly connected with a connector, the end, away from the connector, of the cylindrical drill body is fixedly connected with a plurality of cutting tooth bodies, and the cutting tooth bodies are distributed in a circumferential array mode. The cutting tooth barrel drill comprises a barrel drill body, limiting open grooves are formed in the middle surfaces of the top and the bottom of the barrel drill body, limiting collecting assemblies are arranged on the two sides of the interior of the barrel drill body, and each limiting collecting assembly comprises a first collecting bin, a second collecting bin and a limiting baffle. The problems that due to the fact that an existing cutting tooth cylindrical drill lacks to collect the drilled hard rock chippings in a centralized mode, the hard rock chippings on the inner side of the
