D-Z-BF Taps

Chip Breaker Taps

Especially to be recommended on automatic lathes and multi-spindle machines. The slow spiral flutes will be especially helpful in thread holes beginning with an increased diameter (counterbore or enlarged bore). Provided with internal coolant supply, this tap type will help to solve chip problems on CNC machines.

BF Grind - “Bright Face” grinding in combination with a special edge preparation ensures that chips will break. Short chips will be evacuated without “bird nesting”.

  • 10-15° right-hand spiral flutes
  • Chamfer form E (1.5-2 threads)
  • Chamfer form C (2-3 threads)
  • For blind hole threads
