I was a bit uneasy about buying these due to the low price, but was very pleased at how they performed. The drill bits went through concrete and concrete block with no problem. Highly recommend these.

I finally got around to using these today drilling holes in sanded mortar. When I got through, you could still see the grind marks on the carbide insert from when it was sharpened and the cutting edge still felt sharp so I decided to try an experiment. I drilled a hole in a beer bottle with a hand held cordless drill in one hand while holding the bottle still on a table with the other. I got a relatively clean hole and didn't break the bottle. The drill still feels sharp. I'm satisfied. The reason I took off one star is because they advertised these for drilling wood! I know better, so should they. p.s. I tried it just to make sure.

These drill bits make the most daunting task a piece of cake. These bits melted through a .625 thick stucco wall. I was expecting to brake a sweat. With that said after repeated use. I did experience some performance degradation, but that is expected. In summary these are worth every penny and will get the toughest job done in a breeze. My one complaint is I wish these came in a sturdy hard plastic case. The flimsy platica that it comes in allows the user to roll up the bits and store them in a tool box or work bag, never the less they came in some sort of reusable storage.

A great buy,

They did the one job I needed them for, but when I used them a second time, I noticed the tip on one of them had chipped off already, making it difficult to keep it straight. I ended up making a hole bigger than what I needed, so that one bit is unusable anymore, and I have a wall to repair now.

I was skeptical, but worked like a charm on concrete. I had to install 20+ lights on concrete. It worked fine still not broken.

Best masonry bits ever! I’m always hanging shelves and things in my brick and mortar home and it’s such a pain in the neck. Most of my drill bits break. I got these and they go threw mortar so easily! Very happy with my purchase. I never write reviews but these are making my life easier lol 🤩

Does the job
