A blind rivet is provided to enable drilling and riveting simultaneously without a drilling machine and a riveting tool, self-drill more than two sheets, and insert the blind rivet by integrating a high strength drill blade at the front of the blind rivet. A blind rivet(10) comprises an expansion cylinder(12), a rivet core(16), and a high strength drill blade(13). A hollow part(22) is formed in the expansion cylinder, and one end of the cylinder is formed with a flange(11). The rivet core is formed in the hollow part and formed with rivet core separating cut grooves(15) at a connecting part(14) between a rivet body and a drill blade. The high strength drill blade is attached at the front of the connecting part to penetrate more than two sheets. The high strength drill blade is made of high strength carbon steel or alloy steel.
