PURPOSE: A shaft tube tool for needle type ballpoint tip is provided to improve workability and productivity by conveniently reducing the diameter of a front end by allowing a shaft tube tool to compress a piper for a tip member into a molding hole. CONSTITUTION: A shaft tube tool for needle type ballpoint tip comprises a body(20) and a molding hole(30). The body is formed in a rod shape. The molding hole is formed at one side part of the body according to a center axis. One end of a pipe for manufacturing a tip member is compressed into one end of the molding hole. A shaft tube is formed in the molding hole so that the diameter of the pipe for manufacturing the tip member is reduced.
