PJs,

Good to know and I thought snap technique would work (and even better after making a scribed line). The Dremel diamond cut off wheel should make this easier. I have a diamond wet saw for tile and brick work that might work without shattering the thin carbide if the carbide strip is tightly held and sandwiched in between two 1/2" thick wood boards. This works well for cutting very hard and thin Italian ceramic tiles.

Thanks, Paul
