Most bits were flat or rounded. One even had a bent tip. It looked as if the pins had been clumsily hand-sanded. And I didn't even bother to check that the "dots" were actually centered. The whole purpose of the pointed tips is to prevent the bit from catching on the work piece and being off-center. They definitely won't do the job. I sent them back and asked for a replacement. A few bits were sharp but some weren't so I asked for a refund. Time for another brand.
