yes using a coolant helps in any high speed cutting but be sure to not get much on the dermel unit.

and to echo use safety glasses.

Seems like it's all down to experience from what you're saying. I'll see if i can gather some materials together aswel and try everything tomorrow.

Yep practice is the best way to get good at it.

I used a dremel to cut perspex and the thickness made it a NIGHTMARE task!

When cutting plastics etc do not use too high a speed or it will just melt.

The friction based cutting discs are really not meant for cutting plastics, whereas spring steel cutters are designed for it. They are flexible and very forgiving, I haven't broken one cutting plastic. Also they doesn't melt the plastic so there are no carcinogenic fumes.

Probs best to use deionised water then rather than normal tap water. Sounds expensive haha.

I have goggles, dont worry. Got my overalls aswel just incase!

Thanks for the tip, I'll be sure to pick something like this up next time I am using it in anger versus plastics!

I wish they had this stuff at say your local homebase or halfords/similiar.

Learning a lot here, thank you for the info.

So low speed and gently touch the plexi? Would adding water while cutting help?

water would work, but I think a drop of oil would stay on the work piece better without getting flung all over the place.

edit: as jak731 said get some of them metal cutting discs maplin or screw fix should stock them
