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

VAP (Steam Tempered): - for steel up to approx. 700 N/mm² - contructional Steel - stainless steel - for long-chipping nonferrous Metal (Cooper, Brass, Bronze, Alu) - Zinc alloys - for through and blind holes

Oil Groove:

  • for optimueffect of lubrication of thread depth over 1,5 x D
  • Use graphite lubrication/oil or add another suitable lubricant.
