Single Flute Countersinks should be used when multi-flute countersinks chatter or the hole is too small for a multi-flute countersink to enter.  60° Countersinks are used for centering.  82° Countersinks are used for countersinking flathead screws.  90° Countersinks are used for chamfering and deburring.  100° Countersinks are used to make screw and rivet holes.
