Summary: | A thread-forming tap includes an elongated body having, at first end, a connector portion, and having at a second end, a thread-forming portion. The thread-forming portion includes at least one thread-forming helical thread exhibiting a non-circular cross-section having at least three lobes for plastically deforming an interior wall of a workpiece while forming an internal thread therein. A thread relief portion formed by a helical truncated thread, is disposed between the thread-forming thread and a terminal end of the body. Disposed at the end of the elongated body is at least one radially extending cutting edge for cutting parts of the workpiece interior wall. |
