I built a speed controller years ago (don't think it was a Maplin kit)
so my mate could use his big angle grinder as a car polishing mop. It
had pretty good torque control. It would would work VERY slowly and
was still pretty unstoppable?
I found that my ordinary drill wouldn't go slow enough for some things -
even in low gear. I suppose the lowest it would go was about 200 rpm or
so
- any slower and the motor started to smell. That's why I'm not sure an
electronic speed control would reduce the speed of an angle grinder
sufficiently to drill safely.
why go to all the trouble when you can pick up stuff like this for £8

Most tool stalls have these for around £10.
