It’s a joke

Cordless drills typically have a two speed gearbox. When the tradesman works on price, he uses the high speed gear to get done sooner and hence make more profit. When he works on a day rate he uses the low speed gear to elongate the job and make more profit

I leave my drill on slow setting allways! I think it prelongs the life of it and gives it more torque. though I could be wrong!

Thanks! I have to say that I've come across a good few tradesmen who are very capable of slowing down, and hence making a job more protracted without having to invoke any sort of switch Perhaps 'worse', some are equally capable of speeding up, with a potential consequence in terms of quality of work, when it's in their financial interest to get the job completed as quickly as possible!

I've often wondered what those switches actually do. They are usually 'electrical switches', so not a "two speed gearbox" per se, so I guess it's just a question of motor speed - but I'm not sure of the consequence in terms of torque.

I generally just use the 'high speed' for drilling small holes and the 'low speed' for larger holes and use as a screwdriver (although I often forget to alter the switch!).

More likley they will have a resistor in it John

Very possibly - I didn't suggest otherwise. I merely pointed out that it is usually an 'electrical switch', rather than anything to do with a 'two speed gearbox'. The immediate effect of operating the switch is certainly to change the speed.

But it could also be a switch that opporates a gear box john

Extremely unlikely. If it were operating a solenoid which was mechanically 'changing the gear' of a gearbox, there would be, at the least, a substantial 'clunk', which there definitely isn't
