I bought this set because I was told to learn how to use different beats first before buying a more expensive set. I've been told to replace the ones I use the most. Not being a carpenter just a layman I will never use some of these bits but if I needed them I would get them. I'm glad I did because I didn't use half the beats and probably never will. It's decent quality and a good selection of bits. This is a good presentation and presentation bits for beginners to learn.
