Anti-bit balling PDC drill bit

The utility model discloses an anti-bit balling PDC drill bit, mainly comprising a drill bit body, a PDC composite sheet and bulges at the surface of the drill bit body; the attaching force of rock debris to the surface of a cutter wing can be reduced by the bulges at the surface; when the rock debris is attached to the surface of the drill bit, gaps exist between the rock debris and the surface of the drill bit due to the existence of the bulges at the surface, so drilling fluid enter the gaps, the rock debris can be more easily washed by slurry from the surface of the drill bit and the anti-bit balling effect for the drill bit is achieved.
