Product features
●Suitable for stainless steels tending to work-harden and sticky, as well as chrome steels and molybdenum steels, through hole use.
●Recommended speed : 5 ～ 15m/min
Cemented
Carbide Taps


●In tapping SUS304, SU+SL has more than 3 times longer tool life than SU-PO. Even in 2000 tapping holes, the surface of thread
finish is good and the shape of threads is clearly stable.
●Adopting left hand spiral flutes, compared with SU-PO, SU+SL improves the chip ejection and realizes longer tool life.
