What are the most useful bits for a Dremel/rotary tool, for building and enhancing slot cars and tracks? Which ones cut well in resin and plastic, without getting too grabby or loaded up with debris? Are the polishing bits any good for working on slot cars?

Your basic sanding drums are priceless to me. They do everything from fenders to trimming chassis for me. Plus you can use different grits for finer work.

Some of the smaller milling bits too.

I'll shoot you a pic tomorrow, hitting the sack now :)

Don't forget then fiberglass reinforced cutoff wheels.

The cut off wheels and sanding drums are what I use most. Although I have several milling bits that come in handy especially for resin work, just be sure to wear a dust mask when sanding or grinding on resin. The stuff is nasty on your lungs. ;)

That's just about like the mask I have for painting. :)

Here you go. Its a bulk pack, and they are 1mm thick.

The thin cut-off discs sold by Professor Motor are indeed very thin.

We got a Dremel Stylus - the little handheld pistol-grip version of the Dremel tool. It's vastly better than trying to use a regular bulky Dremel tool or small drill.

As long as we are talking about the high rpm's, DO NOT use the various wire brushes at anything but the very lowest speed. They come apart and send zillions of tiny steel flechettes all over, including you. That's a splinter experience you don't want.

Dremel Stylus with milling bit:



The milling bit was better for hogging out excess resin than I expected. Once long ago I had used one on aluminum and it was too grabby, but on resin it cuts very nicely. The nice handle of the Stylus helps immensely with controlling the tool, and the motor torque is less of a problem than with a normal Dremel.

Late, but here is most in my small arsenal.



Yes, I know...not very organized. But if I cleaned and organized, my buddy Tom wouldn't find anything and get mad.

I keep him happy.
