The invention discloses an inlaid and welded type super-hard drill bit which comprises a cutter handle and a cutter body. The cutter handle and the cutter body are formed integrally. The cutter body is provided with a spiral chip discharge groove. An inlaid groove is formed in the lower end of the cutter body. A super-hard drilling head is welded into the inlaid groove. The cutter point angle of the super-hard drilling head ranges from 120 degrees to 140 degrees, the main edge front angle ranges from 30 degrees to 40 degrees, the main edge rear angle ranges from 2 degrees to 6 degrees, the auxiliary angle ranges from 2 degrees to 4 degrees, the cross edge oblique angle ranges from 46 degrees to 50 degrees, the cross edge front angle ranges from 62 degrees to 64 degrees, the cross edge rear angle ranges from 26 degrees to 28 degrees, and the edge inclination angle ranges from 8 degrees to 10 degrees. According to the super-hard drill bit, the drilling head cannot be abraded easily in the drilling process, abrasion resisting performance is good, the service life is long, workpieces with high precision can be machined, the machining efficiency is high, and the machining cost is low.
