Cutting reinforced concrete posts

Posted by bachgennewydd on July 15, 2006, 9:57 am

I need to cut reinforced concrete posts (about 3 inches square) in my
garden. How easy is this with a grinder? How many discs am I likely to
need per post (I realise I'll need different discs for concrete and
metal). Never used a grinder before!!

A dry diamond blade will be much more efficient. Harbor Freight
has them for about $10 (small 5" grinder type blade) They also
make dry diamond blades to fit circular saws which may be safer
and better.

Reinforced with what? Rebar or wire? I would remove some of the
concrete with a hammer or small sledge (3" is nothing) and then either
cut the wire or cut the rebar and do the same at the other end. If it
is just wire with no rebar I would just demo the whole thing with a
seldge a couple of wacks at the top and at the bottom should be
sufficent.
Good luck
