Rotary tools in support of electronics, Dremel and more ..
G7PSK:
I use zirconium flap disc's for grinding aluminium no need for any lard or wax as the material is made non clogging. There is also a special aluminum grinding wheel which is silver in color and does not need lubricant as it contains it already.

My tip is..
don't rotate it, vibrate it (any woman knows that!)
From a older tread..

Somebody put Foredom in the list. Odd though that nobody has mentioned flexible shaft tools. These blow a typical dremel tool away both with precision and flexibility. They aren't cheap, but a good one with a Jacobs chuck/handle will last a lifetime with occasional replacement of the flexible shaft and brushes. I've owned a Vigor that I bought from a Jewelry tool supply and some other quality miniature tools about 35 years ago that works just as good today. Unlike a Dremel, these generally don't use collets unless you specifically buy a collet style handpiece. It's always hanging there ready to use rather then digging it out of a box or kit. Most of the Chinese knock offs are crap, but a few of them are actually very well made. You don't see these too much outside Jewelry repair, but they are one of the essential must haves in my book. One particular Chinese made unit that was sold by craft suppliers was housed in a blue or green plastic housing that was excellent. The shaft was supple as a hose and the handpiece was a near identical copy of the Jacobs #30 and the foot pedal while plastic was a very smooth speed control, much better I think then mine. These were selling for about $50USD and less at places like Harbor Freight. Most places replaced these with a metal housed unit that's garbage with a stiff shaft and shitty handle, but the Blue one is still around and a much better deal then a Dremel.

You can get flexible shaft tools in varying sizes as well I have seen monsters with 5KW 3 phase motors for grinding. There used to be a very good make called Flextool I have not seen them around for a while another good make was Wolsey they made flex shaft tools as well as sheep shears.

I've an old Dremel of this type I inherited. Much easier to work with than the non-flex shaft versions IMHO as well.
Not sure how it stacks up with Foredom or similar though, as I've not had access to them.
