[Shop-talk] Diamond blade for angle grinder

[Steve Shipley]

Has anyone had any experience in using a diamond blade on an angle grinder 
to cut concrete sewer pipe?
I'm repairing an old sewer line that is part clay and part concrete.  I 
need to trim the ends of the existing
pipe to square them up so I can use rubber connectors to join the PVC to 
the existing 6 inch pipe.

I've got a 4-1/2 Dewalt and an 8 Craftsman grinder to choose from.
