Re: Looking for a source of those RINGs on PCB drills?

Forget the "Spiky" things unless you want to remove a lot of material 
from the wheel in a hurry - good for rough work.

Find a diamond "point" type - they are not too expensive. But you gain 
a lot of control during the dressing.  You can also get a very round 
wheel that has as flat of surface as your hand can move sideways 
across the rest - my favorite type.

Diamond wheels are dressed with a diamond point (from what I 
remember).  However, you have to mount the point in a fixture to get 
it to work good.  When you say you have a couple tool grinders, are 
you talking about the hand held things or what?  Could you be 
referring to a bench grinder of some sort?

I would be surprised if you have a "Tool grinder" as they are usually 
specialized type grinders for grinding tools and cutters.  I have 
never seen one outside a machine shop's tool room.

If you can, send me a picture of your grinder so I can better identify 
it.
