Very strong, versatile bits
I purchased these bits so that I could put up blinds on a metal window frame. I have an old ceramic power drill that could drill through just about anything, but I realized that the problem was the bits that I had was not strong enough to penetrate metal. These bits did not dissapoint. They easily allowed the drill to drill through the metal quickly and easily. I am pleased with this purchase.

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!

Like Cutting thru Butter
Wow, wish I had done better research last year when I had to make holes bigger in order to put wheels on my patio furniture.This year I needed to make mounting holes bigger on shelf brackets. Brackets are made of cast iron. Used the old drill from last year & got nowhere really fast.Took a deeper dive into what kind of drill I would need for my application & colbalt was recommended. I bought these figuring if one breaks or I totally mess up (I am a newbie at all this) at least I have more.Well, no exaggeration, literally 15 seconds per hole & I was all set. These are really great drill bits.

Drilled five 1/8” stainless plates, one bit and a little Mystery oil
I’m always amazed when something really works well. I drilled one hole each in five 1/8” stainless backing plates using just one of these bits. I oiled and kept oiling the work area with Magic Mystery Oil and the bit cut lit it was nothing, nothing I tell you. If anything the bit worked better the more I used it. Very satisfied.
