I use this tool to the fullest for cutting indentations on shelf edges. I trim the lip and then finish it off with a decorative edge to create a nice border instead of a sharp corner. (In a cove you cut a curve somewhere in a tree, seen this a lot, mostly at corners. So it's important - something like this is most likely used to cut full round holes in things I never do, hence may I can't really comment on how well it does it. It's way better than the cheaper nozzle I've used before. Why? It cuts fast, cuts straight and doesn't wobble. Side holes, especially if you don't make a hole every 360 feet , but make a straight funnel, shaped and at the top...somewhat and it hurts to remove it.And when you pull it out you can bend the teeth and cause wobble.It has a clever slot to remove the plug it never hurts a bit and you often don't have to do anything at all. It's not the cheapest thing you can find, but it's worth it because it really is more than cheap - I had both.
