Fluteless Taps (Forming Taps) are threading tools to form internal threads without cutting.The thread is produced by deformation of the material without damaging the fibre structure.
 

 

 

 


Fibre structure of thread forming


Fibre structure of thread cutting

Benefit:

  • 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:

  • Unalloyed and low alloyed Steel
  • Constructional Steel
  • heat resistant Steel
  • Stainless Steel
  • long-chipping nonferrous Metal
  • Zinc Alloy
  • for through and blind holes
