Review on 💡 Lighted Diamond Coated Bottles for Fly Fishing Shops by Jeff Payne

I purchased this 1.25 inch piece when I was planning to drill through the ceramic tile in my bathroom to install a handrail. I never finished this project, but soon after I had to drill two holes. at the bottom of a massive concrete urn. This tool did the job very well. I've also since used it to drill a hole in a thick concrete pool. My drill chuck was able to follow this bit to the point where I had a 3" hole - with the center "post" breaking out every 3/4" or so. I don't know why some manufacturers say these diamond core bits can't be used on concrete which is usually much softer than ceramic. My experience is different, although you might not be able to go that deep due to the short shank of this hole saw (btw a spray gun was used to cool the drill bit).
