I have some sheet metal that I need to cut for a project. It needs to be a
cleaner cut and more accurate than can be achieved with tin snips.
I considered buying a 7 1/4 inch cutting wheel (if they make them in that
size) and using it in my Skill saw.
My brother said he had heard that taking a regular saw blade and turning it
over so it rotates in the wrong direction, works well for metal cutting.
Anyone ever used this method or have any suggestions - pro or con?
Thanks in advance

I haven't found a way to cut metal that is cleaner than tin snips,
tho.
If you are referring to the serrations that happen when you move the
snips forward, you are doing it incorrectly, or have the wrong kind
of snips.
By the way, the finer the teeth on the blade, the cleaner the cut.
Also, a metal cutting blade put into a skill saw may work also, tho
it actually 'grinds' rather than cuts.
I've also used a jigsaw with a metal cutting blade. But nothing has
done it as clean for me as a shear, which is what tinsnips are....

you might find a local ductwork or metal shp who can shear it for you.
best cut that way.
so what are you building?

A sheet metal shop may have plasma and/or CNC plasma as well which will
give you nice clean cuts for non-linear stuff that a shear can't do.

i have used the 'reverse' saw blade before and it worked ok.
I have some sheet metal that I need to cut for a project. It needs to be a
cleaner cut and more accurate than can be achieved with tin snips.
I considered buying a 7 1/4 inch cutting wheel (if they make them in that
size) and using it in my Skill saw.
