As the result of some posts in another thread on making mandrels, I was looking at some sources of drill rod and noted a spec for concentricity. The quoted figure was 0.005".
I think I know what concentricity means, generally; but am not sure I understand how it relates to drill rod and the spec mentioned above.
If anyone can offer an explanation, I would be most appreciative.
Thanks.
