How do you cut copper bar without a guilotine?

[Sunder]

As the title suggests, I have 3mm x 25mm x 500mm copper bar I want to use to connect some very large cylindrical cells.

I was originally thinking a circular saw with an aluminium blade, but surely there is a better method?

Can I use a bolt cutter?

Hopefully helpful. Me? I'd use what I have- from my hacksaw to circ to boltcutters I'm not sure what'd work best.

Actually, at <1/8" copper bar I'd try some snips first?!

I've scored and snapped thicker stuff (5mm); scoring it on both sides with a dremel using the reinforced cutoff wheels till I'm about 1/3 of the way thru the thickness on each side, then snapping it after a couple flexes.

When I didn't have one available, I instead used a utility knife to score thru it, same idea, but I didn't cut as deeply (takes too much time).

I've also used a hammer and chisel.

The first dozen videos or so seem to be industrial machines. Its why I asked here: most quick googles show how professionals do it (with a metal guilotine). I wanted to know how handymen do it...

I'm guessing you're right though. Circ saw or hack saw. I'm hoping I can use a bolt cutter, since I don't have tin snips, and just hoping it won't damage the blade.

@Amberwolf. Will try thay as option 2...

bolt cutters will work too, but they'll crush/deform the ends.

A band saw set up for metal works. Also an angle grinder with abrasive cut-off wheel.

I would agree on the hacksaw with a fairly fine blade would work well or an angle grinder with the 1mm metal cut off disc

copper is relatively soft. I use regular plain cheap metal hand saw. It takes me perhaps 30-60 seconds to cut a copper bar that size if it is steady in a vice.

Hacksaw cuts like butter.

Nippers of all types will deform the ends, it that doesn't bother you they might be worth a try. Perhaps nip and flex will do it.

What I would do is go to Bunnings or some such place and get something like a Craftright 150mm Junior Hacksaw for $4.00 AU and use it to cut all the way through. Or score and flex like AW has suggested. Shouldn't take long.
