And run the drill at the lower speed if it has a speed selector. If not the drill may smoke.

Depends on the drill.  Most of them these days have little fans inside that are directly spun by the motor.  The faster you run the motor, the more air they pull through to cool them off.  And drills that have electronics inside like brushless motors as mosfets also have thermal sensors and will cut themselves off before they overheat and start burning up the electric bits.  If you run these drills slower, you'll trip the thermal cutoff sooner than if you ran it wide open.

I do think you're right about if you pulled out the corded craftsman drill you got from your great grandpappy.

I am just sharing my recent experience. I have a fairly new cordless DeWalt. The first time I run the oil pump it was at high speed and after a few seconds it smoked - it didn't burn because I was able to use it after a few seconds and still today. At low speed I was able to achieve 80 psi of pressure with no problem.
