Spiral Fluted Taps_SP SPR4.0I
  • On Sale Till 31/03/2025

[Features]
・ The grooves are twisted in the same direction as the threads for not only good scrap discharging performance but also great cutting performance.
・ Intermittent cutting of female threads with keyway is also possible.
・ Capable of machining both synchronously and asynchronously.
・ Ideal for machining blind holds as the groove is twisted, continuous small coiled scraps are discharged to the rear, and it does not cause cutting chip clogging.
・ Ideal for tapping especially sticky work materials, plastics, etc. due to its sharpness.
・ The tap can easily cut.
・ Intermittent cutting of pilot holes with keyway is also possible.
