29Pcs Cobalt Drill Bit Set, 135 Degree Tip High Speed Steel with Black and Gold Finish, Stainless Steel, Plastic and Wood with Metal Indexed Storage Case 1/16"-1/2"

These are as expected and have been working well. I have only been using them for a few months, but I have not seen any issues with the set.

Quality is good, and the drill bits do what I need them to do.

A project I was doing required sharp drill bits, the ones I had didn’t work so I ordered these. They drill through steel quite well and for the price I feel they are a good value.

great product

Great for steel!!

I bought these bits to drill into a hard steel rod that was about 1/2" in diameter. My conventional bits barely put a dent in it, and even a cobalt bit I had lying around couldn't hack it (probably since it was old and dull). I bought a ten-pack thinking I would burn up a few of them drilling the one hole, but I was pleasantly surprised that I only needed one, and it went right through the rod with no trouble at all. I did use oil to help cool and lubricate the bit, as it got very hot. I recommend these bits very highly, especially for the price.

good bits did the job i burnt up 6 bits but 1 did the job

The drills seem good, the drill case is pretty tin foil, not to stoked on the case.
