How to Use:

Countersinking is a two step process: pilot hole first, followed by the countersink.
It's effective, but time consuming. However, a wide variety of combination countersinks do both tasks at the same time.

NOTE:

The most important thing to keep in mind when using a countersink is to match the size correctly to the screw being used.
A too large countersink will swallow the head of a screw in what will look like a moon-sized crater;
A too small countersink won't fit the screw head, and forcibly driving the screw in can tear the wood fibers around the countersink.
If you don't drill the countersink deep enough, the screw will remain proud of the surface; go too deep and the screw will seat too shallow.
