The metal sheets are fine. The drills are fine. And the rivets are fine. All good, thank you.

These are very high quality drill bits at a great price. I am a machinist and buy bits from a lot of different sources, but much prefer these in the sizes Spruce has available.

I ordered two #30 Bits in case one went dull. I had to drill out 96 rivets in a Cessna. No problem and I never needed the second bit. I center punched each rivet and the bit never wandered and it grabbed perfectly.
