I almost replaced my bathroom porcelain sink because the faucet hole is too small to accommodate my new faucet. Then, I found a post that suggests using a diamond coated bit to make a hole bigger. I went to Home Depot and Lowes, and they do not carry anything that is diamond coated.I bought this with next day delivery. It mounted onto my 4.5" angle grinder and worked like a champ. I stopped 2 or 3 times during grinding just to check the progress. Overall, it took very minimal grinding (maybe 30 second all together) to grind away 1/4" of thickness. Some porcelain around the hole is chipped, like 1/8" or smaller chips. I don't know if chipping is due to my grinding technique or it's inevitable from grinding. Regardless, the new faucet's base plate will cover it up anyway.I am very glad that I spent $25 and saved $250 from needing to buy a new sink.
