Summary:The invention provides an integral PCD 8-edge contour knife. The integral PCD 8-edge contour knife comprises a knife handle and an integral PCD knife head, wherein the integral PCD knife head is welded on the knife handle, eight cutting edges which are annularly distributed are arranged at one end, far away from the knife handle, of the integral PCD knife head, and the eight cutting edges are integrally formed on the integral PCD knife head; the cutting edge width of each cutting edge ranges from 0.05mm to 1mm, chip removal grooves are formed between the adjacent cutting edges, and the groovedepth of each chip removal groove ranges from 1mm to 2.5mm. The integral PCD 8-edge contour knife adopts the integral PCD knife head, so that the situation that the welding strength and precision of the knife head are insufficient is effectively avoided, meanwhile, the eight cutting edges which are annularly distributed are arranged on the integral PCD knife head, moreover, the cutting edges and the groove depths of the c
