Template:Countersink Bits Buyers Guide
From DT Online
- 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.
