Just drill bits. Nothing special.

I had gone through 3 HSS black cobalt jobber bits (also from Amazon), drilling through 1/4" mild steel brackets prior to switching to these bits. A single bit did the work of the prior 3 bits combined, and it is still almost as sharp as new. A very unexpected and pleasant surprise. I would definitely buy this product, from this vendor, again.

There not the best drill bits for drilling wood deck down to steel, they are only good for 2 to 3 holes
