This allows sufficient voltage to be generated in the field windings to generate a strong magnetic field. You will feel the resistance to the drill as it starts to generate its full output.
My drill is 3000rev/min max so say 2000. I must have let it run for 3 or 4 mins. Hope it works for you.
Cheers,
Dave.
