The present invention relates to a thread cutting tool with a shank and a cutting part, the cutting part having several cutting lands ( 3 ) with interjacent flutes and the cutting lands ( 3 ) having a starting taper ( 3 a) and a guide part adjoining same. In order to produce a thread cutting tool with the features named at the outset which experiences less wear and must be reground less often than conventional threadd cutting tools of the type described previously, it is proposed according to the invention that the cutting teeth ( 5 ) have a chamfer ( 6 ) or rounded area ( 7 ) at their corners.
