How To: Drill a Clean Hole
It's easy to drill a hole through a board. But for both sides to come out looking clean, you've got to use this technique.
Here’s how to drill a hole when you need to see both sides of your work. Drill on the front side of the board until the tip of the drill bit pierces the back. If you go all the way through, the job will look like this. Now turn your work over to the back, set the drill bit in the pierced hole, and finish drilling from this side. You’ll end up with a smooth cut on both sides.
