Problems solved by technology

At present, commonly used drill bits are generally common threaded drill bits. When drilling pipes of this kind of drill bit, the opening to be drilled should be drilled from its center, and then drilled to the required opening. Piping waste from the entire opening drilled can go directly into the delivery pipeline, clogging or affecting the delivery pipeline

Abstract

The invention relates to the field of pipe mounting and maintaining, in particular to a steel magnetizing shell bit. The steel magnetizing shell bit comprises a tool body, a tool handle is mounted at one end of the tool body, the tool body is a cylindrical tool body, a cylindrical cavity is formed in the tool body, the tool body is provided with a magnet, and the other end of the tool body is provided with a blade. The magnet is arranged in the cylindrical cavity of the tool body, and one side of the blade, close to the inner side of the tool body, forms a 10-degree angle with one side of the blade close to the outer side of the tool body. After drilling a pipeline, cake-like steel wastes fall out of the bit and into the pipeline, the circular magnet capable of vertically moving on the inner side of the tool body is mounted on the inner side of the tool body, and after drilling, the magnet can attract the cakelike steel waste, the waste is prevented from falling to the pipeline, the magnet attracts the waste left in the drill hole, and the problem of blockage caused by left waste in the drilled transport pipeline can be effectively avoided.

Description

technical field [0001] The invention relates to the field of pipeline installation and pipeline maintenance, in particular to a steel and magnetic sleeve type drill bit. Background technique [0002] The transportation pipelines of water, oil and natural gas may be corroded, broken and leaked due to long-term daily use or sudden accidents, or branch pipes need to be drilled on the original transportation pipelines. An opening of a certain diameter. At present, commonly used drill bits are generally common threaded drill bits. When drilling pipes of this kind of drill bit, the opening to be drilled should be drilled from its center, and then drilled to the required opening. Piping waste from the entire opening that is drilled can go directly into the delivery pipeline, clogging or affecting the delivery pipeline. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steel and magnetic sheath drill bit capable of tak...
