Nervous using Dremel tool. Need advice.

[JRX]

The best cutting attachment for the Dremel is the diamond coated cutting wheel. It's only $15 but it is SO worth it. It cuts through just about anything like butter and I've not needed to use any other cutting wheel since.

I second that - the Diamond coated Metal cutting wheel is totally worth the
investment - I rarely use anything else for cutting anymore.

But if you want to use a dremel on Plastic those cutting wheels would only
"melt" it as they get pretty hot, so the grinding sleeves you can put on the
rubber wheels work a lot better to take away material from plastic.

I for my part would do it with fine goldsmith saws and Surgery knives - that
leaves you a much cleaner surface on the plastic (but is indeed more work).

Any pictures of these bits that work well on the Supreme.

I use surgery scalpels myself. Very precise. It takes a bit longer, but you're subject to less chance of error. As far as the Dremel goes, I use the handheld, rechargeable battery-powered one. Maybe that's why my results with it aren't the greatest? I'll have to check out those diamond-coated wheels, they sound like the end-all attachment to have!

It's the speed. If your multi-tool can do slow speeds, then you will be all right cutting plastic with most types of cutting wheels.
On some cheaper rotary tools you can only change the power to the motor, meaning that it does have enough torque at slow speeds. It will rev up first and then slow to a halt once the bit touches the surface.

I agree about those sandpaper cylinders though. They have worked quite well for me.
