I have several saws, both pneumatic and electric that use relatively
high speed cutting abrasive disks, including a cut-off saw that were
designed specifically for cutting metal. You use the proper safety
equipment which includes a full face shield meant for this kind of work,
leather gloves, knowledge of the the equipment and how to properly use
it, and usually a leather shop apron and don't forget a shirt or jacket
with long sleeves made of a rather durable material and not a thin
Like an Oxy Acetylene cutting torch it takes knowing how to use the
equipment and practice so you know what to expect if a blade or wheel
My preference for this type of work is the small, air powered, cut off
saw that uses about a 3" diameter, high speed, relatively thin abrasive
disk. I even use a small one with a true rotating saw blade for
slotting tubing. Now there is something that can grab and you do not
want any body parts in the direction that sicker is going to jump. Also
if it jumps you are probably going to be starting over on slotting what
is now a bit shorter piece of tube.
I have to plead guilty to not liking a saws-all. It's just too much
weight and too big to easily handle when up the side of a tower.
