Template:Countersink Bits Buyers Guide

For most non-critical work in Design and Technology, countersinking can be achieved using a Twist Drill twice the diameter of the hole in question.
Combined Countersink, Pilot Drill and Counterbore drills can greatly speed up assembly work in wood.
For more precise work, purpose made Countersink Bits are available.
Choose High Speed Steel if countersinking steel since ordinary Carbon Steel is suitable only for wood and plastics.
