How to Make Cuts Using a Guide Rail


The Festool guide rails, as an accessory, make it easier to rout straight grooves or dadoes. To cut a groove or dado, the bit needs to be positioned on the center line of the cut. Follow these steps to set your plunge router for a grooving operation using the guide system.


  1. Check and adjust the guidance jaws, if necessary, as well as the guide rail adapter for a snug fit with the guide rail (Photo 1).

  2. Mount the guide rail adapter to the router with the guide rods.

  3. Clamp the guide rail to the workpiece, keeping a distance of 5mm between the front edge of the guide rail and the cutter or groove.

  4. Place the guide rail adapter on the guide rail.

  5. Install the height-adjustable support on the router base to support the router (Photo 2).

  6. Align the center line on the platen with the groove’s center line, and lock the router in position (Photos 3 & 4).

  7. You can use the scale on the support foot as an indicator of where to stop the cut (photo 5).

Photos 3 & 4 – On the left (photo 3), the router is misaligned with the center line of the cut. This has been corrected on the right (photo 4).


Photo 5 – The scale on the support foot helps to indicate where to stop cutting.
