The Kreg Jig is a popular tool used in woodworking for creating strong and precise joints. It works by drilling angled holes into one piece of wood and joining it to another using a special screw. The depth collar is an essential component of the Kreg Jig as it determines how deep the hole will be drilled. Understanding and correctly setting the depth collar is crucial to achieving a strong and secure joint. Let’s explore the importance of kreg jig depth collar settings and everything you need to learn about.
What are kreg jig depth collar settings?
Depth collar settings are an essential component of using a Kreg Jig. They determine the depth of the pocket hole drilled into the wood. A pocket hole is a small angled hole drilled into the wood to join two pieces of wood together. It uses a drill bit that has a stop collar that controls how far the bit will drill. This stop collar is also known as the depth collar, which can be adjusted according to the thickness of the wood you are drilling into.
Importance of Correct Depth Settings
Having the correct depth collar setting is important for creating a strong and secure joint. If the depth collar is set too shallow, the screw won’t have enough bite to hold the wood together. On the other hand, if the depth collar is set too deep, the screw will come out of the wood, leaving a hole behind. Therefore, it is important to select the right collar setting for the thickness of the wood being used.
Additionally, using the correct depth collar setting can help prevent splitting of the wood. When the pocket hole is drilled too deep, it can cause the screw to put too much pressure on the wood, causing it to split. This can weaken the joint and even ruin the project.
How to Read a Depth Collar?
Reading a depth collar is easy once you understand its parts. The collar consists of three parts: the stop collar, the locking ring, and the adjustment screw. The stop collar is the part that sets the depth of the drill bit. It is adjustable, allowing you to set the depth of the hole according to the thickness of the wood being used.
The locking ring is used to lock the stop collar in place once you have set the depth. This prevents the collar from moving during the drilling process. The adjustment screw is used to adjust the tightness of the locking ring.
To read the depth collar, simply look at the markings on the collar. These markings show the depth setting in 1/16 inch increments. For example, if the collar is set at the fourth marking, it means that the depth of the pocket hole will be 4/16 inch or 1/4 inch.
