[QUOTE="chucktee, post: 3613197, member: 104300"]Those are called hole saws. The centering bit will drill a hole all the way through the board, and the toothed cup is intended to drill (or [I]saw[/I]) the larger hole all the way through as well, although you could carefully watch the depth and stop before that happens. The biggest trouble with a hole saw is that it does nothing with the wood between the larger circle and the small hole of the centering bit. You'll still need something (like a router!) to remove that material. If you want to drill flat-bottomed holes, look for Forstner or multi-spur bits.
