Vevor diamond drill bits
The product is as described, have not had to use them. I have been researching these bits at other retailers and found that this product is as good in quality as much more priced name brands. For the price, I would recommend this product.

Drilled through 8\" cinder block with no problem.
Drilled through 8\" cinder block to shorten dryer exhaust pipe. Dryer works much better and should result in lower energy usage.
MC PETTI MC PETTI
This worked really well, BUT!
This worked really well drilling through the side of a concrete storm sewer. BUT! I had to buy a $240 hammer drill. This will not work in standard 3 tooth chuck of the hammer drill I already had.

Did the job
Worked great, only drilled one hole so far but it worked great
Chad Lincoln Chad Lincoln
Gets the Job Done
As others have mentioned, the pilot is pretty useless and failed shortly into my core. However, this bit got through my 8” solid concrete foundation wall (took about 30 minutes). Not sure if it would be good for any future work as it slowed down towards the end, but it paid for itself on the one use.

Works
I bought this with the intention of drilling a single hole through a hollow concrete block for a dryer vent. For that purpose, it worked like a charm. I was able to get through the front half off the block before burning out my cheap 20 year old drill. Another better drill finished the back hole.I saw one review that said the drill bit was too short. That was not true for me.I cannot speak to the longevity of the bit, but for the single hole I needed, this was a great value.

Great looking drill bit, especially for the price. Teeth a little thinner than expected, but will give it a try.

Easily bored through a 3 wythe red brick wall
The core bit cut though the brick without much difficulty. The pilot drill however does stay lock into the adapter regardless how hard I tightened the hex screw it always wobbled free. Only used it once so no real review on longevity or durability.
