Dies Spiral Fluted Taps (for blind hole) DPO HSS Spiral Pointed Dies Spiral Fluted Taps (for through hole) Specification Front face ■Due to the effect of spiral pointed flutes, DPO pushes out chips toward the cutting direction and reduces the troubles caused by chips. For icon explanation, refer to P.50 ■DPO due to its design can be used one side only. ■DPO combined with YAMAWA RD-DA die holder (P.315 or Spiral Pointed Taps (for through hole) 636) can be easily applied on machining center.
