Center Drills, Centering Tools How to use
I've heard that processing a thread with a roll tap does not produce chips and the tool life is better than with a cutting tap. I am planning to switch from a cutting tap to a roll tap to take advantage of the extra benefits. Please tell me about features and processing points I should look for before I start using it.
