Straight and Sharp
So far, these seem to be well made, straight and sharp. They drill aluminum cleanly but I haven't used them on steel yet. So far, so good.

FIFTH COMPNY WAS THE CHARM , HAPPILY GOT ER DONE
I tried 5 different Cobalt bits. Ordered from 3 different companies. They weren't sharp. Sent them back. Took a chance and ordered from a 4th company with good reviews for sharpness. A gain the bits were not sharp. Dent them back. Thought I would give it one more fifth try from this company. HURRAH !! Opened the package , took a bit out and tried it. IT DRILLED THE HOLE IN MILD STEEL ALMOST LIKE BUTTER. THEN DRILLED 2 MORE HOLES WITH THE SAME BIT. NO PROBLEMS DRILLED THEM EASILY. WOULD DEFINATELY RECOMEND THESE BITS. ARRIVED IN ONE DAY. VERY SATISFIED.

Durable and Sharp, But Could Last Longer
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 bought these drill bits in 1/8 1/4 and 6.5mm for drilling out stainless steel rivets. They worked very well. Drill at slow speed for best results on SS. The 1/8 size, extra care is needed as they are small and break if to much pressure is used Never broke any of the larger sizes

Can't say much about these bits, I expected to blast through the pack as I had at least 400 holes to drill but I only needed just one bit.
