I recently discovered a used 115v 90 degree angled drill which is very useful for drilling horizontal holes through floor joists in situ. I had bought this a few years ago and put it somewhere safe and then forgot I had it.
However, these are usually powered from a heavy isolating transformer for outdoor work where you do not want mains voltages.
However for indoor work where mains voltages are not a problem, is there any good reason NOT to use an SCR or TRIAC controller?
