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.

●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
  • Carbon steels：S45C ～ S50C
  • Aluminum alloy castings and die castings
