Sawing a groove - that's how it works

Again and again one comes into the predicament to require a groove on a workpiece. Which tools are optimal for this, and how you can also help if necessary, you can read in detail in this article.

Use of grooves

Grooves are needed for different purposes:

  • for example, to set a wooden board at a 90° angle in the middle of another board
  • to lay a cable in a board
  • to make a drawer extension
  • Etc.


The production of a groove is usually done with the router. Depending on performance and manufacturer routers can be quite different in price. The prices range from around 50 - 80 EUR for already quite good devices up to 500 EUR and more for professional devices.

The purchase is usually worthwhile because routers are a very universal tool. In addition to grooves, it is also possible to mill edges and profiles very precisely, and most routers are also very well suited for copy milling. The work results are thereby highly precise.

Groove with the router - step by step

  • wooden board
  • router
  • suitable cutter

1. Determine and mark the position of the groove exactly

Clamp the workpiece firmly and securely so that it can not slip. Mark the position and the course of the groove with a pencil. Put on the router by trial and error and position the rip fence in a suitable position.

2. Prepare the router

Mount the desired milling cutter on the router. Set the appropriate milling depth. Select the appropriate speed.

3. Milling

Switch on the router (previously press switch-on inhibit). Release clamping lever. Guide the cutter into the wooden board and move the router along the guide swiftly. At the end, operate the clamping lever and guide the cutter out of the board. Switch off the cutter again.

Important when milling

It is important when milling that you milled as possible in coordination with the wood fiber. This ensures significantly better and cleaner milling results without fraying or tearing the material.

Alternative to making a simple groove

Basically nothing works as safe and visually perfect as a router. In case of emergency, if no router is at hand and you only need a quick groove, you can drill with the drill many small holes next to each other.

Then you "connect" these holes by simply pushing the drill from hole to hole. The result is visually not usually nice, but if necessary usable, for example to lay a cable through a board.

Tips & Tricks

A router is also useful for customizing the edges of home-made furniture. It is a true universal device with a variety of uses. Also for wood joints you can use the router well.
