I'm very satisfied. Compared to cheap tap drill bits from local store (still more expensive than this set from Banggod) these bits are excellent. I tried one of them on a piece of iron (see attached pictures) where bits from local store weren't of any help and the result is perfect. I'm just a DYI hobist, not professional, so I can rate only based on my limited experience, but I think at least for occasional use these bits will be more than suitable. Just to be clear I used the bit in electric drill to drill a hole only, then removed the bit, put into handle and did the taping slowly by hand. It went without applying force, the bit was sharp and even I proceeded carefully turning the bit backward few times, it wasn't necessary and it would work also in one go.
