Drilling tool

The utility model relates to a drilling tool which is mainly applied to accurately positioning pipe fittings in the process of drilling so as to ensure processed holes to be located at positions meeting the specified technical requirements. The drilling tool comprises a fixing tool mechanism and a positioning mechanism, wherein the positioning mechanism is mounted between a first support seat and a second support seat of the fixing tool mechanism and on a tool bottom plate of the fixing tool mechanism, and a support bottom plate of the fixing tool mechanism is fixedly mounted on an operation platform of a bench drill through screws. The drilling tool is simple in structure and is reasonable and skillful. The drilling tool is convenient to operate and overcomes the difficulty in positioning during traditional drilling process. Accurate positioning can be realized by adding the positioning mechanism on the basis of an existing tool, so that processed parts can meet the technical requirements, thereby guaranteei
