I have a tile countertop. The additional outlet for an added Microwave is under the cabinet. My Microwave just quit. (Quite old) on that Microwave I cut the plug off put the cord thru a 3/8 hole and put a replacement plug on the cord. My wife insists that is a stupid hack job and wants a hole big enough for the plug to fit thru.
What is the best method to get this hole drilled.
Thanks in advance, Kevin
