Two blades would sure help the balance problem. Mine has only one blade. I have cut many holes with it, however using a hand drill. It's a bit challenging, but can be done. A little scary when you're doing something like cutting a hole in a door to install a lock set since you only have one shot to get it right!

They are available several places, I got mine at McMaster Carr supply. They say these things are only good for drill presses as they are challenging. I've often used it to *draw my hole and then I've used either a sabersaw (4 inch or bigger) or a router to cut away the material when I didn't want to go through with the spinners.
