Good quality economic bits. I just liked cutters because I could make end caps with an electric hand drill without using a drill press. You need to hold the drill firmly, not press too hard on the wood, just let the drill hook into the wood. There is some run-out, but the bit hardens relatively quickly and produces a straight, tight-fitting plug when Forstner bits are used on the hole. I'm sure the claw type tapered bits need to be made with a drill press. Can't comment. But I recommend this set, mainly due to the fact that with the help of straight chisels you can make corks without a drill.
