Roll Tap Series Spiral Fluted Taps (for blind hole) SC-TL-RZ Torqueless Thread Forming Taps with short chamfer Spiral Fluted Taps (for through hole) Specification Coating 1.5D Spiral Pointed Taps (for through hole) Recommended Tapping Speeds depending on Materials ow carbon steels Medium carbon steels High carbon steels Alloy steels Stainless steels 15〜30 15〜30 15〜25 15〜25 10〜25 Hand Taps For icon explanation, refer to P.50 Product features ●Producing high quality internal threads with little burrs, SC-TL-RZ results in longer tool life. ●Tapping hard-to-machine materials of lower ductility becomes possible. Cemented Carbide Taps ●Longer tool life under water soluble oil. ●Wider tapping application range up to higher speed tapping. ●Applicable materials: • Stainless steels：SUS303, SUS304, SUS316, SUS440C • Alloy steels：SCM420 Roll Taps • Carbon steels：S45C ～ S50C • Aluminum alloy castings and die castings Special Thread Taps Simple Inspection Tools Tapping data Tapping condition [ M3×0.5 ] Work material SCM440 tempered SC-TL-RZ Previous tap 32HRC Tapping depth 4.5㎜ After 7,000 hole tappings After 2,800 hole tappings Pipe Taps Bored hole φ2.8 Tapping speed 5m/min Machine Tapping center Tapping fluid Water soluble oil (×10) Thread Mills （Ｎ・ ） 123 Compared with previous tap, SC-TL-RZ have 100 less damage even after 7,000 hole tapping. 100 Dies 55 50 44 0 SC-TL-RZ Previous tap Center Drills Torque　　　　　Thrust Centering Tools JIS RO-23 518 For improvement, spec may change without advance notice.
