Query: Excellent buy

Excellent quality tool. I am a 35 year professional mechanic and hate paying high prices for anything that I don't need to. These drive bits are as good as anything on the market but at a down to earth price. I have seen lots of garbage tools in my time and was a little hesitant to buy these tools. I was very pleasantly surprised at the good quality of this purchase.
