Review on 5/8 Inch Diamond Finger Milling Bits For Enlarging Holes On Porcelain Tile Ceramic Marble Granite - Raizi 1 Pc by John Kahsar

Revainrating 4 out of 5

Works as expected in my review

I needed to grind our porcelain sink faucet hole about a 1/4” bigger. It worked out well. Quite pricey though for a grinding bit, but compared to other grinding bits pricing, it’s about the same.

Pros
  • This bit is great for smoothing the edges of an existing hole. this is not for making holes.
Cons
  • The product may not work effectively on harder materials, such as quartz or granite

I needed to enlarge three holes in existing tiles, increasing the diameter by about 1/4". This diamond bit, in my old Black and Decker angle grinder did the job in short order and without cracking the tile. I should add that the tile was mounted on old ferrocement backing (expanded metal and cement motor). It enlarged the backing material as well. Very pleased.
