TM 9-254 4-27.  Hand Tap Nomenclature - Continued t. Rake.  Any deviation of a straight cutting face of the tooth from a radial line.  Positive Rake means that the crest of the cutting face is angularly advanced ahead of the balance of the face of the tooth.  Negative Rake means that the same point is angularly behind the balance of the cutting face of the tooth.  Zero Rake means that the cutting face is directly on the center line. u. Root.  The bottom  surface joining the flanks of two adjacent threads.  The root of an external thread is at its minor diameter, while the root of an internal thread is at its major diameter. v. Spiral Point (Chip Driver).  A supplementary angular fluting cut in the cutting face of the land at the chamfer end. It is slightly longer than the chamfer on the tap and of the opposite hand to that of rotation. w. Thread  Relief.    The  clearance  produced  by  removal  of  metal  from  behind  the  cutting  edge.    When  the  thread angle is relieved from the heel to cutting edge, the tap is said to have "Eccentric" relief.  If relieved from heel for only a portion of land width, the tap is said to have "Con-eccentric" relief. 4-28.  Thread Limits.
