I was looking to cut a lot of holes in thin metal, but they needed to be of various (and sometymes non-standard) sizes. The cost of a lot of hole saws was more then I wanted to spend...or had. The local hardware store had the answer. It's an adjustable fly cutter. You chuck it in you 3/8" drill, the bit has an adjustable bar on 90 degrees from the bit. Loosen the allen screw, set the distance from the bit to the cutter (carbide I think) to 1/2 the size of the hole, tighten the allen screw, and cut a perfect hole. By adjusting the bar, you can cut any size hole up to about 6" or a little more. Total cost of the flycutter...$8.25!! Cut a few holes for a friend or two and it pays for itself. Hope this helps...tnv
