As mentioned by another reviewer, my set was also poorly packaged and some of the bits had chipped and damaged cutting edges. The foam that needs to hold the bits securely is very cheap and too soft. The bits I usually use are made in Austria, these are made in China. I'd rather pay a little more and get a solid set of bits that will last for years. I do not recommend this item even if the price was half what is normally sold at Revain.
