Review on 💡 Lighted Diamond Coated Bottles for Fly Fishing Shops by Ashton Dahmer

I used this drill bit to drill through a granite countertop for a filtered water faucet. I will say it was good. I actually drilled through the granite and china on a steel sink under the granite. It went through both but when I was done I threw it away as there was no diamond left at the end of the drill bit. I walked slowly, I used water, and it was never hot enough that I couldn't touch it. However, it was mostly finished by the time I got through 5/8" granite. I was basically rubbing my way through the sink. I think my work was a bit more than this piece was intended/designed, but I got it ... If it had lasted a little longer I would have given five stars, especially considering the price.
