### ⭐⭐⭐⭐ Tooth Broke BUT Bluerock is making it right
*by R***I on March 24, 2023*

EDIT: Bluerock reached out to me and has offered to send a replacement bit via 2 day shipping which we have accepted. Hopefully the broken tooth was just a rare occurrence, the bit did seem to work well (and probably would still drill with a broken tooth but using it that way is not recommended). Thanks Bluerock for standing behind your product. Original review: I'm not sure what the expectation is of these bits but it worked ok, however after about a dozen cores in cured concrete sidewalks (about 4"-6" thick) I realized it was missing a tooth. I'm guessing it would still cut but everything I read said not to use them if a tooth is missing. We used plenty of water and drilled slowly without applying too much pressure so I'm not sure why this bit failed.
