In order to ensure pin-point pilot drilling you would usually use a center punch to

mark the exact spot; however on thin metal sheets this could damage the surface. With very slow rotation of the drill spindle you can prevent the tip from slipping off the sheet metal surface even without marking the spot with a center punch beforehand. This speed can be adjusted electronically and is called pilot drilling speed.
