Dormers forming taps differ from cutting taps in that the thread is produced by deformation of the component material rather than the traditional cutting action. This means that no swarf is produced and the resultant thread is stronger.
Forming taps obtain a very high productivity rate and a long service life specifically in low alloyed steels, stainless steel and aluminium materials.
It is built with the ability to allow a chip-proof operational process and a robust thread in through and blind holes.
