Best Countersink Drill Bit Sets

What are countersinks?

A countersink is a type of drill bit used to remove material from a hole before drilling it out. A countersinking tool removes material from the bottom of the drilled hole so that when the drill bit passes through the center of the hole, it will not damage or chip any surrounding materials.

If you want to make sure your drill bit does not damage the surface around the hole, then you need to ensure that the drill bit will pass through without damaging anything else.
