I would buy the carbide tipped hole saw but not Dewalt. Buy a Champion CT5 in the correct size you need. I have not had much good luck with Dewalt drills bits and saw blades. On the other hand the Champion CT7's I have bought are still going strong.
Use a good drill motor and a little care the CT5 will last many times the number of holes you have to drill. Keep the rpm's reasonable for the size of hole you are cutting also.
I have not used oil on thin metal, but on thicker stock I do use cutting oil.
