We are processing a screw thread with a roll tap. We've been using a GP and NP thread plug gage for inspecting the internal thread function and fit, but I am worried about the minor diameter of the thread created with a roll tap. I need to know if the thread's minor diameter is within the tolerance of the 6H standard. Is there any tool to check the bored hole after using a roll tap?

You can check the minor diameter of an internal thread created with a roll
tap and check the amount of material deformation that is formed into the minor
diameter from rolling the thread by using the check pin CPC-S.
