Hi, my name is Chris Palmer. In this segment, we're going to talk about how and when to countersink screws. Countersinking a screw is when you sink the screw below the surface of your work. Any time you want to fill it with spackle or a plug, you want to countersink it. Also, even if you're leaving it open, it looks a little better if the screw has a nice neat countersunk hole around it. So, there's a couple different ways to do it. With the first method, what you need is a bit that is larger than the head of your screw by just a little bit and then also a bit that is slightly smaller than the shank of your screw. You can do it in any material. Here we're going to drill some nice clear hemlock so you do the big hole first. You don't need to go very deep, just the thickness of the head of your screw. After you have the countersink drilled in the surface, you go ahead and drill the pilot hole for the screw and it's right, the center is marked for you already. Now, all I have to do is drive the screw home, and it should look really good. Another way to do this is to purchase a countersink bit. This is neat because on one end it's got a drill bit for your pilot hole, and here is your countersink bit, and then you flip it around and there is your driver all in one, all in one handy spot. So, the pilot hole and the countersink hole get drilled at the same time. Now you flip the bit around to your driver and drive the screw home. Thanks for watching. I'm Chris Palmer. That's how you countersink screws.
