Review on 💎 Yosoo Diamond Ceramic Porcelain with Coating by Russ Mashlan

We recently ordered a new bathroom faucet and it didn't fit the US standard sink hole so we had to widen the hole. At Home Depot or Lowe's diamond hole saws are $25-40 a bit, then some of them require a bit. So I turned to Amazon, found a great video on this bait and tried it with my husband and it worked great! Not only did it cost $4 but I got the right size, they don't have certain sizes in the store and I didn't need one bit, this bit goes straight to the drill! If you have the same problem as us, the trick is to use a slightly damp drill bit and work slowly with porcelain or granite.
