Re: Thread tap suggestion
roll taps = form taps which is the bulk of what I use
Just remember that a larger tap drill size is need as they are not cutting metal away but rather displacing it into the shape of threads. There are several places online that list the proper sizes as well as alot of new drill charts are including them as well.
