Seems to be a good product
Used one of these the other day and worked great on 14 ga. mild steel. Don't use these as much as I did before for work, but these seem strong and sharp.

Great!
These BECOLLO drill bits are the best I’ve used anywhere. I was trying to drill a 3/16” hole in a 5/8” pc of old cast iron and I had several to do. I burned up every 3/16 name brand and off brand bit I had, probably 5 in total, with not even one hole drilled. I took a chance on these and I can’t believe how sharp and durable these things are. They drilled through the old cast iron like it was hot butter. I finished the hole I had started and drilled 5 more holes with ONE bit and it’s still sharp! I now own every size of these bits they sell on Amazon and they are all great.

Lasting quite well
I bought 5 different sizes of this brand of bit and I've been really happy with them. I mostly use them on mild steel, so your mileage may vary if your materials are harder.

worked like a charm on aluminum - very sharp, clean cutting edges on these drill bits
I have not tested yet on any kind of iron or steel; check back later for any update . . .
