The Amoolo 1/4" Cobalt Drill Bits are sharp and cut through metal, wood, and plastic with ease. They don’t overheat quickly, and the precision is great. The value for a 10-pack is solid.However, I noticed they wear out faster than expected when drilling through harder metals. For light to medium-duty work, they’re excellent, but for heavy use, they might not last as long. Overall, a good buy for the price!

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.

The drill bits worked well. Stainless steel is very hard so I needed to use a couple of them to get through some smaller outdoor stainless steel brackets. I would recommend.
