Roll Taps ●This is most suitable for tapping with water soluble cutting fluid. ⑥ Tapping Data Special Thread Taps Simple Inspection Tools Tapping condition [M6×1] Tapping Length ⑦ Tapping Length Work Material 50C Tapping Speed 15m/min Machine Machining center, vertical type Tapping Fluid Water soluble cutting fluid Incomplete thread Incomplete thread Pipe Taps Tapping Length 13mm, blind hole ⑧ VUSP 1.5P VUSP(Chamfer 2.5P) Thread Mills Premium Thread Mills Internal thread surface Internal thread surface ⑨ Dies ⑩ Center Drills Centering Tools ⑪ JIS ①-13
