The invention provides a two-level cutting scraper blade. The two-level cutting scraper blade comprises a drill bit body, screw threads, a water channel, shackle grooves, three cones, three scraper blades and a water hole; the water channel is arranged inside the drill bit body, and an opening on the top of the water channel is arranged at the center point of the top of the drill bit body; the upper part of the drill bit body is provided with screw threads, the shackle grooves are arranged below the screw threads, and the shackle grooved are formed in parallel in two positions at the left sideand right side of the drill bit body; and the three cones and three scraper blades are welded on the bottom of the drill bit body, and the water hole is formed in the bottom of the drill bit body. According to the invention, by improving the traditional scraper drill bit and cone drill bit, the two-level cutting scraper blade has the advantages that the structure is reasonable, the mechanical drilling speed and application range of the drill bit can be improved by virtue of two levels of cutting, the blade is good in stability, small in load, small in abrasion, good in gauge protection effectand scraper blade is not easy to damage and the like, thereby effectively solving the problems and overcoming the defects proposed in the background art by the invention.
