Mini drills are one of those tools that you don't need often, but
occasionally they are *really* useful. My Dremel 3000 just died, web
search suggested triac failure as a common fault, so I replaced that,
but it's still dead. I guess I might have cooked the adjacent timing
chip when replacing the triac. (When I get round to it, I might bypass
the control circuit and add an external speed controller. Should have
said that armature and field coils seem OK and there is negligible brush
wear).

However I could do with an immediate replacement. A bit reluctant to get
another Dremel, there are numerous clones at around half the price on
eBay and Amazon, does anyone have any recommendations?

My Duratool ones (CPC own brand I believe) seem pretty OK and are
certainly very cheap.

Don't think it's a CPC own brand as I've seen them in Maplin.

I have seen them on, and bought them from, Amazon.

Ah, here is some info.:

bypass the controller.

They're called die grinders.

Proxxon look handy but not cheap.

If you have a compressor,die grinders beat the dremel types hollow.

I have a compressor and a die grinder, but I certainly would not use
this for (for example) drilling half millimetre holes in beading, to
take panel pins.
