I’ve found a much better cutting tool than my circular saw for the occasions when I have to cut vinyl or sheet metal — a 100-millimeter disc grinder. It’s a lot more maneuverable than a saw, and the blade and cutline are easier to see.
For sheet vinyl, I use a masonry blade in the grinder. It actually burns away the material and produces a smooth cut every time, regardless of the outdoor temperature.
For cutting aluminum, steel roofing or flashing, I replace the masonry blade with a metal grinding disc. And this is one job when I really do wear my goggles.

Dear Jim (Billman),
I don't see a date on this, so forgive me if response is very late. I have used a utility knife but could not maintain a straight line. Do you make a template of floor with red rosin paper and then follow a scribed outline with your grinder? Thanks! Sincerely, Andrew
