Review on 💎 Diamond Countertop Porcelain Bathroom Installation Cutting Tools: Superior Precision for Perfect Placement by Michael Glassburn

Not worth it. The shaft is smooth and chrome-plated. The patron has nothing to crack. The drill kept losing grip on the shank, and then the drill stopped spinning and fell on the drill. I stuck with it and ended up drilling a hole in the travertine tile, which is relatively soft; However, I'd be better off spending $35 and getting a good quality version from a hardware store.
