Spiral Fluted Tap Series Spiral Fluted Taps (for blind hole) SU+SL Spiral Fluted Taps for Stainless Steels, Through Hole Use(with LH spiral flutes) Spiral Fluted Taps (for through hole) Specification E 2D Oxide Spiral Pointed Taps (for through hole) Recommended Tapping Speeds depending on Materials ow carbon steels Medium carbon steels Stainless steels 10〜15 10〜15 5〜15 Hand Taps For icon explanation, refer to P.50 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.
