Cut off the dowels

A dowel does not always fit completely into the borehole. But then you do not necessarily have to buy shorter dowels or use other attachment methods. You may also be able to cut off the dowel. What has to be considered when cutting anchors, we have summarized here for you.

Procedure if the drilled hole is too short for dowels

A borehole can not always be drilled deep enough in the wall or ceiling. But then the dowel is usually too long. You now have several options:

  • They use shorter dowels
  • possibly the use of liquid plugs or injection plugs
  • They cut off the long dowel

The cutting of the bracket is limited possible

The cutting of the dowel basically works. However, this may well limit the carrying capacity of the anchor. You should therefore consider cutting a dowel only if you do not later "hang" too much weight on it. In addition, you can not cut off a dowel arbitrarily. You should cut anchors by a maximum of 25 percent.

In addition, you must also differentiate according to the technical nature of the dowel used. In principle, you can cut cavity dowels (made of metal) as well as all-purpose dowels or plastic expansion dowels. The most commonly used dowels are the expansion dowels.

Cutting plastic dowels

Insert the dowel into the drill hole. Now you can deposit the protruding part with a utility knife (cutter knife or Stanley knife). You can also mark the dowel and then cut it with a fine jigsaw.

Cutting off metal dowels

For metal dowels, it is a bit more expensive. Here you must preferably use a fine metal saw. So you should mark the dowel length to be shortened and then cut off the dowel well outside the borehole.

Shortening different dowels (according to technical design)

You can even cut cavity dowels. Insert the cavity plug completely into the drill hole. Depending on the version, you must fold out the spreader wings with a special dowel tong. Make sure that the plug is firmly in place. Now you can easily cut off such a dowel.

Tips & Tricks

Not always the sole cutting of the anchor is sufficient. Then you can additionally secure the dowel. You can fill the hole with flash cement, resin cement or other strong hardening material and insert the shortened dowel. After curing, you can use the dowel. These and other ideas can be found in the guide contribution "dowels in old buildings".
