Let’s find out about each type of joint, one by one.

Through Dovetail Joint

The through dovetail joint is the most common joint used in different types of woodworks. It looks similar to a finger lock where two hands are tied together. From the outside, the joint parts are clearly visible. This type of joint is used to make different types of box making and carcass building. In the case of making drawers, the joint is referred to as an English dovetail joint.

It is also named a plain dovetail joint by many carpenters. Back in the day, carpenters would mask the joins with a veneer, but it is left shown in later times. This has become one of the most recognizable factors of a through dovetail joint.

Half-Blind Dovetail Joint or Single-lap Dovetail

Also popularly known as the single-lap dovetail joint, the half-blind joint is kind of the other pole of the through dovetail joint. The reason is, its end grain here is completely hidden on the boards, opposite to what we see on the through dovetail joint.

The end tails are housed by the sockets to make sure that the ends are not visible from the outside. This type of joint is widely used for joining fonts of wooden drawers.

The only difference between a single-lap dovetail joint and the through dovetail joint in the end grain of the joints is visible in the through joint and invisible in a single-lap dovetail joint.

Secret Mitred Dovetail Joint

The Secret Mitered joints are popularly termed as full-blind Mitred joints. This specific type of joint is basically applied in making box and cabinet making. Arguably, this is the strongest type of joint among all the dovetail joints we know. That’s why the joint is used in places where a strong connection is required.

 Secret Double-Lapped Dovetail Joint

A different version of the Secret Mitred dovetail joint is the secret double-lapped dovetail joint. It’s basically the same, but it comes with a visible portion of the end grain of the joint’s single edge. This almost looks like the secret Mitred one, but it displays a narrow part of the end grain of the joint’s end.

Basically, the double-lapped joints are applied to the construction of carcass and box that needs the dovetails to be kind of invisible.

Sliding Dovetail Joint

The sliding dovetail joint is a bit different than the other 4 types of joints. It’s not the typical end-to-end joint that we have seen so far. Rather, it’s about joining two different wood boards at a 90-degree angle. The joining is quite different than the other types as one wood piece goes sliding into the other. The intersection happens through the sliding of the tail of one wooden board into the hollow socket of the other board in the middle.

Apart from sliding dovetail joints, the joints are also known as French dovetail joints. The most common use of this type of joint is the cabinet shelves joints, frames of tables, table frames with attached parts, front rails to the cabinet sides, etc.
