Pocket hole joinery is a popular method of joining wood pieces together. It is a simple technique that involves drilling a hole at an angle through one board and into another, then driving a screw into the pocket hole to hold the two pieces together. One common question that arises when using pocket holes is whether the hole is supposed to go all the way through the wood.
The answer to this question is that it depends on the situation. According to a post on Woodworking Talk, drilling all the way through the wood can result in raised fibers around the exit hole area, which may require sanding or carving to smooth out. However, if the joint requires a through-hole, then drilling all the way through is necessary. As a general rule, pocket holes are designed to be drilled only partway through the wood, leaving enough material for the screw threads to grip onto.
Understanding pocket holes and the tools and materials required for pocket hole joinery is essential to properly executing this technique. Knowing when to drill through and when to stop short is an important aspect of the process. With the right tools and knowledge, pocket hole joinery can be a reliable and efficient method of joining wood pieces together.

Understanding Pocket Holes
Pocket hole joinery is a popular method of joining two pieces of wood together. It involves drilling a pocket hole at an angle into one of the pieces of wood and then attaching it to the other piece with a screw. The pocket hole is a simple and effective way to create a strong joint between two pieces of wood.
A pocket hole is not supposed to go all the way through the wood. Instead, it should only go partway into the wood, leaving a small amount of material on the other side. This is because the pocket hole is designed to create a strong joint by pulling the two pieces of wood together. If the hole goes all the way through the wood, it will not create a strong joint and may even split the wood.
To create a pocket hole, a pocket hole jig is used. A pocket hole jig is a tool that helps guide the drill bit at the correct angle to create the pocket hole. The jig also helps to ensure that the pocket hole is positioned in the correct location on the wood.
Pocket hole screws are specifically designed for use with pocket hole joinery. These screws have a special shape that helps to pull the two pieces of wood together tightly. They also have a self-tapping feature that allows them to be driven into the wood without the need for a pilot hole.
When using a pocket hole jig, it is important to pay attention to the thickness of the wood being used. The thickness of the wood will determine the length of the pocket hole screw that should be used. The thickness of the wood will also determine the spacing between the pocket holes.
In summary, a pocket hole is not supposed to go all the way through the wood. Pocket hole joinery is a simple and effective way to create a strong joint between two pieces of wood. A pocket hole jig and pocket hole screws are essential tools for creating pocket holes. When using a pocket hole jig, it is important to pay attention to the thickness of the wood being used to ensure the correct screw length and spacing between pocket holes.
