[J.D.]

Let Uncle Goku explain this.
65mm= stock size.

65.25mm(or .25mm) means it is 1/4 of a millimeter over stock. This is metric measurement.

When they say .010, .020, .030, etc, this is standard measurement. .010 over means 10 thousands overbore, etc. .010 thousands is equivalent to .25mm over. .020 over is equivalent to .50 mm over, etc.

Any other questions I can clear up?

I knew .030" over and the like.

But .5 over is .5mm over. now I got it.
