I wish there were instructions, but it's just a tool kit and nothing more. The larger hole saws are easy enough to use, but I couldn't figure out how to use the smaller hole saws, luckily I didn't need them for my project. It's good for cutting plastic and for the cheap price I would probably buy it again as I don't plan on using tons of hole saws in the future. If you plan on using it a lot I'd go with something of better quality, but for a little work from time to time it will work just fine.
