Volkel M92 x 4.0 HSS-G Serial Tap Set

Serial taps comprise of one or more undersized roughing taps which remove most of the material before final sizing with a finishing tap.
Some reasons for using serial taps are:
The roughness of the material being tapped.
The amount of material to be removed could cause swarf choking with a single tap.
The very small tolerance on pitch diameter.
An extremely good finish required.
