I'm planning to cut a large number of bricks where I want exact and clean cuts. I was thinking that it should be possible to put a diamond cutting blade on my Dewalt miter saw. I find discs with the right diameter (230 mm) but all I find have a center hole of 22.2 mm. On the miter saw, the hole is 30 mm. Are there no discs with a 30 mm center hole? Reduction rings 30 > 22.2 do exist, but the hole on the blade needs to be larger. And drilling larger holes doesn't seem stable
