Taps and dies are cutting tools used to create screw threads,which is called threading.a tap is used to cut the female portion of the mating pair(e.g.a nut)a die is used to cut the male portion of the mating pair(e.g. a bolt).the process of the cutting threads using a tap is called tapping,whereas the process using a die is called threading.both tools can be used to clean up a thread,.which is called chasing.

The quality of HSS tools are basically decided by HSS raw material and heat treatment. We can

 keep a strict control of these procedure.
