First of all, the product illustrated on Amazon looks like they are Titanium Nitrate coated, which they are not. They may be high speed steel, but they are not very sharp. However, at $9, you kind of get what you pay for.

I liked that they provided a small box for them to be in, which is handy. I didn't like that they were completely different from those pictured. Not Gold but a dull gray color throughout. It was very dissapointing because I decided to buy them based on the look of the product as well as the functionality.

If you’re wood working with these they may last forever. I used them to make a custom router table regarding the flush top dropping screws into a rather simple setup. I milled through aluminum and after running a wire brush over the blades after each use they continued to plug without slowing down on my drill press. Only made 8 holes with a single bit, but I was impressed.
