Which grinding disc is best for cutting plastic?

[JBrennand]

I need to cut some 2-3 mm thick plastic piping, would either a metal or stone angle grinder disc do the business - and which would work best ?

Or is there another one you'd recommend ?

It's the smallish 115x22 disc size I need - the thinner the better.

Cheers John

Not likely ! It's a cooker hood venting pipe 8 ft in the air and tucked behind the top of the unit's decorative fascia over the oven. There is little space to work in there and hard to get an angle. Needs to be a quick in and out !

Use a slitting disc.

The thinner the better (I've seen them 1mm thick)....use a masking tape edge to cut to, and try not to let the heat build up i.e cut a bit at a time.

yes, the thin discs for stainless will do it
