Fragging Maze Brain

I have a maze brain that needs fragging. from what i read it is difficult. any suggestions?

 

Diamond Blade Band saw

 

If you don't have a band saw, which is highly likely, you can use a dremel or even a hammer and chisel, although that way is messier and you are more likely to have some damage.

 

Best way is with a Wet Band Saw designed for cutting tiles etc.

The problem with straight dremel or band saw use is that you burn the coral while you cut it which causes more damage than you'd care to have.

Using a Wet Saw alleviates that issue.
I've seen it done where someone does small short cuts with a dremel and sprays water on the coral between passes.
