The invention discloses a crash pad of a scrap-suction hood. The crash pad comprises a hollow cylindrical crash pad body arranged on the lower end portion of the scrap-suction hood; a baffle ring is arranged on the upper end portion of the crash pad body; a plurality of positioning holes are evenly formed around an axis in the crash pad body; an annular groove is formed on the lower end portion of the crash pad body. The crash pad of the scrap-suction hood made of flexible materials is simple in structure, reasonable in design, convenient to mount and demount and capable of effectively buffering impact force upon a processed workpiece by the scrap-suction hood, so that scrap-suction effect can be improved, cutting scraps can be effectively removed, and accuracy of the processed workpiece and drilling quality are improved.
