The way I cut ½” flexible steel conduit is I first crack it like a
crab at the point I want to cut and when it separates I cut it with
side cutters. A while back I had taken out about ten feet of it from
an old house for some reason I don’t remember now. It was in real good
shape so I saved it in case I needed it some day. So a few days ago I
needed a short enough piece and I remembered that old conduit I had
saved. I measured it and grasped it with both hands and tried to crack
it at the point I wanted to cut. Either they have different grades of
flexible steel conduit and nobody told me or they must have made those
extra strong in the old days because there was no way I could crack
it. It was like trying to bend EMT with my bare hands. I finally had
to cut it with a hacksaw.
