Hi
Do concrete posts & gravel boards contain rebar or something similar?
If they do, wot kinda disc is best to cut them with (9" ankle grinder, as my mates wife calls them)?
I guess rebar would damage a diamond disc?

They have very thin (about 4mm) steel bars through them, yes....only usually two per post and the same in each panel.
It's not affected my cheap grotty 9 inch DD which set me back a fiver
As stated two thin bars normally, about as thick as a pen perhaps.
I just kept on cutting with the diamond disc. lol.
