In article , Harold & Susan Vordos says...

Abandon the use of the edge finder and use a dial test indicator. Mounted
in a drill chuck for easy turning, you can locate the center of your hole
far more accurately than by other methods, and it's fast.

A toolmaker's button here makes the job a good deal easier.

If he's interested in +/- 0.001 accuracy, then an edge finder
would be fine. If he wants better than than, use the indicator.

But in all cases a postive feature is easier to pick up than
a negative one.
