if you use the right size drill there is no need for any tools. Look to letter size drills also and 64th sizes. I also do most of my machining off the belly holes so I need them to be precision. Mine go in snug and after epoxy I challenge anyone to remove them, without ruining the plug. Every time I see Stan K. he tells me about that tool, been well over a 15 years now. I just tell him to use the right size drill
.I am also not a fan of the counter bored hole look. i like the smooth grommetized look much better, but to each his own. just my useless 2 cents, peanut gallery, devils advocate, observation.
