There aren't many reviews here. This is Bosch. It works exactly as it's supposed to. It's sharp, it's pristine, it's a tool you can handle with confidence. The best compliment you can give for something like this is that it becomes "natural". This is because there are no issues, and it's so good that the user doesn't have to worry about the sleeve slipping or the bit not turning. Just drop it and go to town. I've struggled a lot with cheap countersink sets, but no more. It's funny how picky I am when it comes to my power tools, but with something like this (a relatively inexpensive item) I've always looked for the cheapest. Ha! What an idiot! The best drill won't work well if it doesn't have a good attachment. This is something you'll be using a lot in woodworking, so spend a few bucks more and get this set. It will serve you for a lifetime and save you from countless curses and disappointments.
