Review on Diamond Porcelain Hole Saw Extractor by Joe Duncan

These cheap hole saws live up to expectations. I bought four different sets of these tools and they all worked as expected: I made at least one cut. Some of them have pleasantly surprised me with four or five cuts when cutting ceramic tile, while others have made one cut in granite and gone in the trash with no regrets. Just don't expect to pass them on to your sons and daughters and you will be satisfied. As mentioned, it's very important that the work surface is damp (the sprayer and helper are great for drilling at ridiculously slow speeds and don't use excessive force. Remember: you're actually sanding here, not cutting, so be patient and let the tool do the work at your own pace.
