This probably is a good value for hobby purposes. I like the variety of cutters and the relatively low cost. That said, I've noticed that these cutters do not perform as well as more expensive cutters when working with harder materials. These tend to cut slower and will burn hardwood.The units I received had a 3mm shank, which is slightly less than 1/8 inch. Not a problem in some cases, but they can slip in 1/8 precision collets. My Dremel tool has an adjustable collet, and that worked fine.
