Wooden dowels

Dowels of different sizes, smooth and fluted, with and without bevels

Wooden dowels , originally just dowels , are connecting elements in wood processing . They are used in solid wood and wood-based materials for butt joints and miter joints in carcasses, as well as for smooth and profiled frame corners and T-joints.

Wooden dowels are available in different designs:

In the most common form, dowels are pieces of smooth or fluted round rods. They are usually made of beech wood in different lengths and diameters with already bevelled ends or as meter pieces to cut to length. They are usually glued into holes with a corresponding diameter, with the glue being better distributed over the entire length of the dowel thanks to the corrugation. In the case of dowels with a smooth surface, the glue is stripped off when inserted into the drill hole. The bevel makes it easier to insert the dowels.

Another form is the angle dowel, which can be used for miter joints. It is angled by 90 °, mostly made of laminated wood and grooved.

Expansion anchors are suitable for connections with high tensile strength. They have grooves (sometimes also crosswise) and are mechanically compressed. When inserted into the borehole, they swell again when using water-based glue. This creates increased contact pressure and better toothing.

There are dowel irons and dowel sharpeners for making your own dowels, especially from high-quality types of wood . Dowel irons are steel plates with openings in the common dowel sizes, which create smooth or corrugated dowels when punching through dowel blanks. The bevel is then cut with dowel sharpeners.

There are also wooden dowels made of plastic .
