The speed can be set to any value within its
range.

the mechanical resistance which can be felt is
overcome.
The bit is not yet fully tightened!
Continue to turn, exerting firm pressure (you
must hear a clicking noise as you turn) until it
cannot be turned any further - only now is the
bit safely tightened.
