Abstract

The invention discloses a drill bit with long service life. The drill bit comprises a drill bit body; a wear-resistant layer is arranged on the surface of the drill bit body; a corrosion-resistant layer is arranged on the side, far away from the drill bit body, of the wear-resistant layer; a high-temperature-resistant layer is arranged on the side, far away from the wear-resistant layer, of the corrosion-resistant layer; the wear-resistant layer comprises wear-resistant pimpled rubber, a ceramic polymer coating layer body, a high-temperature coating layer body and a crystal nucleus new material layer body; and the ceramic polymer coating layer body is located on the outer side of the wear-resistant pimpled rubber. The drill bit with long service life has the advantages that the wear-resistant layer, the corrosion-resistant layer, the high-temperature-resistant layer, the wear-resistant pimpled rubber, the ceramic polymer coating layer body, the high-temperature coating layer body, thecrystal nucleus new material layer body, a primer layer body, a coal tar enamel paint layer body, a petroleum asphalt layer body, an epoxy resin layer body, an organic silicon layer body, an inorganiccoating layer body and a fire-resistant protective coating are arranged, so that the problem that the service life of a traditional drill bit is not long enough can be solved, the service life is long, and the drill bit is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of drill bits, in particular to a drill bit with long service life. Background technique [0002] The drill bit is a cutting tool used by ordinary drills or drilling machines to cut out circular holes. The basic principle of the drill bit is to make the drill bit trim and rotate, cut the workpiece, and then remove the drill chips from the drill groove. The commonly used drill bits are mainly There are twist drills, flat drills, center drills, deep hole drills and nesting drills. Although reaming drills and countersinking drills cannot drill holes on solid materials, they are also customarily classified as drill bits. , because it requires high-speed rotation, the quality requirements of the drill bit are very high, otherwise it will face the situation of frequent replacement, and the service life of the traditional drill bit is not long enough, which not only brings inconvenience to the use, but also brings ...
