The invention relates to drill bits for drilling in the fields of oil-natural gas, mine engineering, building foundation engineering construction, geology and hydrology, in particular to a rotary jet flow PDC drill bit which comprises a drill bit body, knife wings and PDC cutting teeth. The knife wings are positioned at the crown of the drill bit body, the PDC cutting teeth are positioned on the knife wings, a cavity with the lower end open is arranged in the drill bit body, a diversion plate, a compression cavity and a storage cavity are sequentially arranged in the cavity from top to bottom, the compression cavity is communicated with a dendritic runner penetrating the diversion plate, a main body of the dendritic runner is of a hourglass-shaped structure with two ends wide and middle narrow, and a rotating element is arranged in the storage cavity and composed of a rotating element body and rotating blades spirally arranged on the periphery of the rotating element body. The rotary jet flow PDC drill bit is simple in structure and high in impact capability and mechanical drilling speed, secondary abrasion of the drill bit caused by rock debris is avoided, and service life is prolonged; a reverse nozzle joint structure is adopted, so that energy consumption of well drilling is lowered.
