These materials have remarkably high work hardening properties. ⑤ ●The optimum design of the thread section reduces the processing burden on each flutes cuttingchamfer. ●Reduces cutting resistance and increases tool life. ●Chip discharge is stable and achieves a good surface finished. ●Improved strength and life expectancy is achieved. ●Use with either synchronous or asynchronous thread processing. ⑥ Tapping Data Tapping Conditions [Ｍ6×１] Workpiece Material ＳＵＳ３０４（９０ＨＲＢ） SU+SP Bored Hole Size φ５．０ Can Continue Tapping length ９ｍｍ, blind hole ⑦ Tapping Speed ８ｍ/ｍｉｎ SU-SP Machinery Type Vertical machining center (perfect synchronous feed) 0 250 500 750 1,000 1,250 Tapping Fluid Non-water soluble cutting oil (chlorine-free) (Number of holes tapped) ⑧ Speed chartTaps for blind hole tapping of stainless steel.
