These are well made and a real time saver. Good conical drills. I almost didn't buy them because it seemed like too much. But I took the pill and I'm glad I did. Also, the case is a good way to keep them all together and it's decently made. Never used cork tongs or hex holder so don't worry. Overall a solid set. I would even recommend them to casual users for their time savings (no tossing, dropping, and re-tossing).
