HSS-E Roll forming tap,TiN coated
Used for thread forming in copper,brass,aluminum,low carbon steel and stainless steel materia

   Forming taps(roll forming or cold forming)produce threads by deforming the material near the hole walls,rather than by cutting the material.  this method  often works well in ductile materials. however,in brittle materials it often results in unsatisfactory threads. torque requirements for forming taps are considerably higher than for cutting taps. when forming taps are used,chuck capacity must be decreased by 25%. forming taps do not produce chips.
