Problems solved by technology

[0002] In mechanical processing, it is generally necessary to drill the workpiece. Drilling requires a drill bit. Drilling is only for rough machining, and then it needs to be reamed, repaired and other finishing processes. In the prior art, it is all done by replacing Drills and cutting tools are used to work, so the quality of the processed products is uneven, and it is inevitable to produce defective products, which takes a lot of time and affects the processing efficiency; the drill needs to use lubricating oil during maintenance, and it must be cleaned before and after use. It is necessary to apply lubricating oil to ensure the service life of the processing drill bit, but this method is cumbersome, and sometimes the operator will forget it, which will have a certain impact on the service life of the drill bit

Abstract

The invention relates to a drilling tool. The drilling tool comprises a tool handle and a tool head connected with one end of the tool handle, the tool head comprises a connecting block, a drill head arranged on one head face of the connecting block, and a tool connecting disc arranged on the other head face of the connecting block, the drill head is arranged at the center of the connecting block and coaxial with the connecting disc, an axle hole is formed in the end of the tool handle connected with the tool head along the axle center, the axle hole is matched with the drill head, the length of the axle hole is consistent with that of the drill head, an oil hole connected with the axle hole is formed in the tool handle, and a steel ball for controlling the lubricating oil flow in the oil hole is arranged at the joint between the oil hole and axle hole. The drilling tool is featured with simple structure, high processing efficiency, high processed product quality, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical tools, in particular to a drilling tool. Background technique [0002] In mechanical processing, it is generally necessary to drill the workpiece. Drilling requires a drill bit. Drilling is only for rough machining, and then it needs to be reamed, repaired and other finishing processes. In the prior art, it is all done by replacing Drills and cutting tools are used to work, so the quality of the processed products is uneven, and it is inevitable to produce defective products, which takes a lot of time and affects the processing efficiency; the drill needs to use lubricating oil during maintenance, and it must be cleaned before and after use. It is necessary to smear lubricating oil to it to ensure the service life of the drill bit, but this method is cumbersome, and sometimes the operator will forget it, which will have a certain impact on the life of the drill bit.
