Through hole

NORIS STABIL

For through hole threads up to 4 x D

NORIS-STABIL machine tap for through hole threads up to 4 x D. Due to the special geometry of the STABIL- flutes, the chips are effectively evacuated ahead of the tap avoiding the possibility of chip-packing.

  • For almost all materials
  • For steels with good machining capacity
  • For highly resistant and heat resistant steels up to 1400 N/mm²
  • For stainless and acid proof steels up to 1100 N/mm
  • For nonferrous metals
  • For soft materials
  • For Titanium and Titanium alloy

NORIS DL15

For through hole threads up to 4 x D

NORIS-DL15 machine tap for through hole threads up to 4 x D. Due to the special geometry of the flutes, the chips are effectively evacuated ahead of the tap avoiding the risk of chip-packing.

  • For Titanium and Titanium alloy
  • For Inconel 718

NORIS trapezoidal single cut taps

For through hole threads up to 2 x D

NORIS-trapezoidal single cut taps for through hole up to 2 x D. Through the good chip breaking the trapezoidal thread can completed in one cut. The resulting chip volume is removed in the cutting direction.

  • For steels with good machining capacity
  • For stainless and acid proof steels up to 1100 N/mm
