Buy some decent crank bolts? They shouldn't be loose, and they definitely shouldn't chip while you try to loosen them.
actually what happen was that the original crank bolts was too wide for the campangolo chainring, so I end up getting a shorter one, I replaced them all with the shorter one unfortuantely one of them refuse to come out and need to be drilled to removed it, that why I couldn't replaced just the one asap.

The Miche bolts are defintely quite weak.
