...like a Ridgid #276 or Reed SC49-6. What are the cutting wheels
made of? How easy are they to ruin?

My brother is a school teacher and wants to get a bunch of geodes
(hollow rocks) for the kids to break open. From what I've read, they
are commonly cracked using a soil-pipe cutter, which start at $350.
If he rents one, is he probably gonna ruin the cutters and have to
buy a new chain for it when he turns it in?

Thanks, regards,
Bob


Hmmmmmm. A soil pipe cutter wouldn't have been
my first choice for cutting rock (though I haven't
tried it...)

For a really low-budget operation, how about a
masonry (abrasive) saw blade in a circ saw or
even a chop saw?

Better, a diamond blade with water cooling to
control dust.

Either way, just cut partway thru and split with chisel.
