IF (and this is a BIG IF), the edge to be trimmed will be hidden by the refrigerator, the a hand held diamond blade angle grinder may to the job. As mentioned above this is a very dusty project, and the dust is extremely abrasive. I is most likely that a wet process could not be used. An alternative that is slower, but less dusty is to use a stone (carbide) blade in a reciprocating saw. If you can not find a company to do this, you may need to do this yourself. I have the tools, send me a PM if you would like to discuss further.
