Review on CUP BUR ASSORTMENT Cup Assortment by Carlos Macy

Pretty good range of drill bits. I haven't used them all yet, but the ones I've used work well. I've used them to round off the wire ends of the earrings I make. Works quite well, but not perfect. I'm actually surprised they don't work better. However, they get the job done. With practice, I'm sure I'll learn how to use them. It is very convenient to have several sizes. The shank size is smaller than my Dremel tool can use, but a couple of paper sleeves will solve that problem. I could also buy a supplement, but I don't want to spend any money on it.
