I haven't used a angle grinder yet but you could use one we use them at work to cut plastic pipes, I've used a jigsaw and a Oscillating multi tool which worked really well plus then it had other bits which cleaned up edges

Angle grinder and diamond disc works a treat on most plastics, always my choice for IBC and PVC pipes. I recommend wearing a dust mask though

I used a cutting disc too on my 5" grinder. But the thinnest disc you can, cuts much faster.
I would have used my "hand me down" Black and Decker jigsaw from the 1970's but the blade flew off when I started cutting with it

I recently cut my first IBC for my first AP system. Started with an angle grinder, as that is what i used for the metal cage, then switched to a 8" circular saw. Found the lines came cleaner and a hell of a lot straighter. Used a hand file to clean up any burrs after. I have also slit a 12mm poly tube (from my retic) and capped the edge all around, tied it on with small cable ties and it looks neat.

Just my 2c

having just cut up my IBC and 55 gal barrels I found a jigsaw with a hacksaw blade worked best.
makes a bit of a mess with tiny bits of plastic all over... but cuts pretty well.
You have to clean up the edge tho, but just run a stanley knife (utility knife) over the edge and clean off the bits left behind.

Too scared to use a wood bit in my jigsaw when cutting plastic... did that years ago before i was clever... only did it once

Hi, I just cut 2 IBC's and found jigsaw with wood blade very easy to use. I also tried a wood hand saw which also worked pretty good but left larger teeth marks on edge than the jigsaw did. Both cleaned up pretty good with angle grinder run across them.
Next one I used jigsaw for most of the work and wood saw on thicker plastic bits and where plastic uneven.

I used a skilsaw very successfully to cut about 8 or 10 totes. I set the guard for about a half inch, roughly 10 or 15 mm. I drew a line on them when the liners were still inthe cages. I sat a 2x4 on the rung and ran a marker down it. When I took the liners out I layed them on their sides and pulled the guard up to start the circular saw then cut. It makes a neat and straight cut. I had no problems.

For the cage I used a sawzall, reciprocating saw, with a metal cutting bit. All 8 to cut the cages and liners took less than an hour at a leisure work pace.

I think cutting with a recip saw would be hard to get a straight cut. An angle grinder the same and slow too. The advantage with the other saws over the skilsaw (circular saw) is safety. The skilsaw is the most dangerous tool I own I think.

Hand saw. The cheap orange handle variety from big B is remarkably versatile and very easy to control... Angle grinder with cut-off wheel for the cage.

5" grinder with masonry/diamond disk, like butter on the liner and doesn't leave the gritty residue on the plastic.
Yhen just need to swap to a cutting disk for the cage.

100mm angle grinder and diamond blade (disk) They are cheap as at about $8, (Bunnings or Mitre 10 or your local hardware shop whatever), and they last forever almost. Plus if needed they can cut pavers, bricks, etc etc. BUT be careful. It is an angle grinder after all. Cheers and Beers. (are you allowed to use brand names in the forums? If not sorry.

I have a dual saw for birthday and it can cut through anything like car tires.

What do you do with cut up car tires...

It's for when the neighbours piss him off...

I use an oscillating hand tool, although I haven't tried it on a cage yet - the sander attachment cleans up edges very nicely. That comes later this week.

I have old car tires lying around doing nothing so I be cutting them down and painting them to make a boarder out of them. But with a Dual saw it can cut through steel, plastic and wood with same blades.
