The blue ring machine tap for general, wide-ranging applications in long-chipping, non-alloyed steels up to a strength of 850 N/mm².
  • Cutting geometry precisely tailored to steel materials

  • Optimized micro-geometry and diagonally stepped threaded part for high process reliability and longer service life compared to comparable machine taps
Notice
  • Sufficient coolant and lubricant must be added when cutting threads.

  • For the machine tap/material assignments, see the overview tables
