Cutting stainless steel unistrut with a porta band.

[zappy]

This is my first time working with stainless steel Unistrut, so I got to cut it with a Portaband, and It was impossible. Do I need to use a grinder instead or a chopsaw? Thank you for your help.

You need the right blade, some WD40 as cutting oil, and don't try going slow- SS work hardens so you need to take the biggest/hardest bite you can (same goes for drilling, press hard). That said, I'd probably use a sawzall with a carbide blade (or a chopsaw).

Vinegar works well as lube on SS.

Grinding SS can be bad. Any hot work on SS produces "hexavalent chromium", really really bad for you.
