What is the power difference approximately between a 700w motor and a 550w induction motor in a pillar drill ?

Are you talking about brushed motors vs induction motors? It really depends
on the design of the motors in question.
I feel that brushed motors generally have more torque, but there are
induction motors with control circuits these days that compensate for
saturation effects.

Mine is a 500w induction motor and have rarely found it lacking in torque.
Although I only ever use the lowest speed gearing anyway.

The previous one was IIRC 350w and prone to stall when using things like a
hole saw.

Of course as with everything, you can never have excess power. ;-)

You can actually be too thin, that can be the evidence that its killing you.

You can obviously be too demented, you subnormal auto-contradicting senile

Almost exactly equivalent to having a five legged horse and chopping a leg off.
But much depends on whether they are genuine UK/IEC horses fed on hay or chinese
ones fed on rice, fruit bats and snake remains

550W correctly reduced in speed via a pulley system and preferably a steel
geared gearbox will mean, at least with a correctly sharpened drill bit, you'll
easily be able to drill 1 inch diameter holes in mild steel plate. Restraining
the item you are drilling could be the bigger issue.

If it's a chinese horsepower without gearing then it could be 1/4" in plastic or
wood

A 1" twist drill? Crikey. ;-)

I have a set of 'blacksmiths drill bits' that go up to that size
(diameter g). I mainly use them when counter boring softer materials
on the lathe as they are quicker than say a 13mm bit then boring bar.
