Blind hole

NORIS SL

For blind hole threads up to approximately 2 x D

NORIS SL machine taps with a 15°/25°/30° right-hand spiral flutes for blind hole threads up to approximately 2 x D. This type produces excellent results in difficult cutting conditions, particularly threads with cross holes. With the chip evacuation against the cutting direction, a secure tapping operation is assured.
The tool is available with or without internal coolant supply.

  • For almost all materials
  • For steels with good machining capacity
  • For highly resistant and heat resistant steels up to 1400 N/mm²
  • For Titanium and Titanium alloy
  • For Inconel 718

NORIS SALOREX

For blind hole threads up to approximately 3 x D

NORIS-SALOREX machine tap for blind hole threads up to approximately 3 x D thread depth. Due to the high spiral helical flutes the chip evacuation against the cutting direction is assured, even for deep threads. The tool is available with and without internal coolant supply.

  • 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/mm²
  • For high alloyed steels up to ~1100 N/mm²
  • For nonferrous metals
  • For soft materials
