These Forstner bits are probably my top 5 favorite tools in my shop. They cut a clean hole that is perfectly matched to the nominal size. I've been using them for a few months now and they still cut just as well as the day I got them. I highly recommend them, I'll be getting a metric set soon too! The box isn't fantastic, but it does the job perfectly. I drilled a few holes in a block of wood to attach to my tool wall, so I don't really care about the quality of the box.
