grinding wheel for rough trim of acrylic

[Kacey]

What's the name of the wheel that some of you use to do the rough trimming of acrylic from the retainers? Also, from which company do you purchase them? Thanks..

Here I use a 3/8 Cratex. They are a green wheel, remove a fair amount and leave a smooth finish.
I purchase mine from my local rep from Patterson. I am sure most other lab supply houses have them as well.

I use the brown cratex lathe wheels.
