The S series is special taps that combine tapping and rolling cutting functions in one. The cutting edges for initial full thread cutting edge feature TAFLET RELIEF with non-flute tap; therefore ,the TAP feed force is adjustable. This fully eliminate female thread enlarge problem even tapping soft steel.
Once the female threads are cut, then TAFLET RELIEF machining is applied by non-flute tap. This provides more smooth and beautiful thread flanks than that of only cutting motion.
