Classic thread cutting

Conventional tapping is the most common machining method for making internal threads.

Machine taps

Extensive basic tap programme for different applications and materials.

  • Various geometries and surface coatings to choose from, depending on the material to be machined
  • Different flute forms, depending the kind of hole to be worked in
  • Choise of tolerance (standard, oversize, ….)
