Me too. It's mighty handy for keeping sharp bits. Took some practice to get the sharpening down but it was worth it.

To me the bits are so cheap that if they get dull I just buy new ones.
Sharp bits are definately key for doing any sort of "precision" work at all though.

Good drill buts aren't really all that cheap.

Good drill buts aren't really all that cheap.

I have 3 or 4 sets of cheap bits and I can never tell which ones are sharp, so I think having a way to keep them all sharp is better in the long run

I'm pretty much sold on a Drill Doctor, I just need to see where the best price is in town (or online).

Thanks for the good info so far.

Keep coming with any other tips for precise drilling techniques.

Steady hand, good eye, and a good grinder is the key to a sharp bit. Drill doctors work great just more setup. Good bits are not cheap, and dont' be fooled by coating and the work titanium. HSS or Carbide are the only way to go and american made would help everyone out including yourself.
