Can/Should I use an angle grinder with a blade for metals on PVC coated metal?
Using an angle grinder you're going to end up with melted PVC clogging the blade, and possible fire from hot metal/sparks that you are grinding igniting the plastic, etc.
As such, the suggestion to use a reciprocating saw (effectively a form of power hacksaw) is valid - however, since you already own a hacksaw, and it does not seem like it should be such a huge job, I would suggest that possibly your hacksaw blade might be dull, if it's &quot;doing nothing to the steel&quot; and that a new, sharp, hacksaw blade might be a very different experience. Hacksaws are made to cut steel, but a dull blade won't cut much of anything. Hacksaw blades are replaceable precisely so that you can have a sharp one easily (they are not generally considered to be practical to sharpen.)
