Bit cuts well: sharp and very clean cut. However, just to be clear, on this pre-order list I asked a question if the bat came with a small case or storage box and someone answered yes. It's not like this. Supplied in a small transparent plastic bag. No downside, because it doesn't matter. The bit shank has the model number engraved on it, but it would be even better if they also included the bit size. There is also some rust in the engraving. Not bad and no worse than some other engraved steel tools but not as good as others.
