Review on 💎 Diamond Coating Ceramics: Top-Notch Porcelain Ceramic Cutting Tools by Michael Weaver

I was not happy with this industrial and scientific product after I put it to the test. The hole saws couldn't even cut through ceramic properly, let alone porcelain. The only positive thing is that it comes with a nice case. However, the poor quality of the tool is not worth the high price. Save your money and invest in a better product.
