Havent had a chance to use the bits but when package arrived the metal bit holder was bent and the rivet hinge was broken.. very thin holder cheaply made. I hope the bits are better quality

The the drill bits are OK if you use them very, very carefully (I think they are over-hardened, or not temper -relaxed) and will break easily. The holding box is a joke, it arrived fallen apart and 10 - 12 pieces of very tiny drill bits were all over the larger shipping box, some broken apart. After 5 times opening the box it doesnt close anymore. The lowest quality tool I ever bought. Not worth 10 bucks.
