I received a very timely phone response to my inquiry from Mr. Fuller in which he recommended the 4" right-angle grinder with a diamond tip blade. This worked great for making the circular cut. Additionally, since I had a only a small number of straight cuts, I was able to use the grinder for all the straight cuts as well, thus saving the need to obtain a wet saw. Thanks for your great advice.
