Abstract

PURPOSE: To make the work efficient of burring, with an imperfect screw portion itself partially removed, by using a guide part, screwed with a worked perfect screw portion being the guide, and a tool, with a cutting edge part provided for removing an imperfect screw portion.
CONSTITUTION: On peripheral surfaces of a tool main unit 6 of the removal tool, for removing a burr 4 of an imperfect screw portion 2, is provided a screw-ahape guide part 5, which is screwed into a perfect female screw portion 1 to guide an axial direction of the tool main unit 6. In this case, a gap of about 0.02mm is provided between an effective diameter of the perfect female screw portion and that of male screw in the guide part, and to play a role of guiding the tool main unit, is provided the male screw part 5 of about three threads. And a cutting edge part 7 is provided for cutting to remove the imperfect screw portion 2, simultaneously with a linear-shape cutting edge of screw thread pattern provided which is divided into n so a height could be changed by stages circumferentially in the thread length of outside 1 pitch and is further in a phase relation shifted from the screw thread on extension of the screw portion of the guide part 5.
