I used a cheap hole saw off ebay to do my 10mm adaptor plate (38mm) and it was perfectly up to the job.
Use the low ratio box on your drill and drown it in WD40 constantly, If it gets hot you'll kill it.
Think I needed 3 batteries of my 24v drill to do it although they don't last that long these days.
Also I'd disagree with sebs comment about starting small, as your gonna need to be using a holesaw if you start small then the next size up will have nothing for the center to center on and youll never get it to start cutting a circle
