Tap with improved guidance |
摘要 |
Tap working by removal of metal. The invention relates to a tap whose guide part has been modified so as to eliminate any possibility of its cutting. The modification consists in making an undercut over all or part of the outline of the thread so as to prevent contact between the cutting edge and the thread which has just been cut during tapping and/or tap removal operations. <IMAGE>
