Application

Advantages:

  • longer endurance as cutting taps
  • higher possible cutting speed
  • steady exactness of dimension and profile
  • high stability of the forming threads
  • high security against fracture
  • no removal of swarf, no jaming of swarf

Application:

for chipless production of internal threads

bright:

  • for nonferrous metal of good ductility
  • for long-chipping nonferrous Metal (Cooper, Brass, Bronze, Alu)
  • Zinc alloys
  • for through and blind holes
