<p>These are the three dies that I need to tap the blind hole in the front-facing medal section. Each one puts on a progressively shaper screw thread. Because this is a blind hole, I need the thread to start as soon as possible in the top of the hole otherwise there may not be enough thread to make a good connection with the screw.</p>
