This thickness gauge will replace the Festool OEM thickness gauge for woodworkers that use imperial measurements. This is a simple upgrade that will reduce the time needed to calculate metric to imperial which will ultimately speed up your processes.

We've had great feedback for our Imperial Thickness Gauges. The first version has been a huge success, but we've received feedback from numerous people that the indicators are hard to read under certain lighting. We listened to the feedback and our v2 implements a new highly durable, scratch resistant and easy to read indicator. The indicator measurements are contrasted to allow reading in nearly all lighting environments.

  • Changes out metric thickness gauge to imperial measurements for USA woodworkers - 7 settings for common board thickness in USA
  • Easy to read measurements on the side in all lighting environments
  • Measurement indicators uses a highly durable and scratch resistant label
  • Installs in about a minute by removing a single T10 screw


7 Settings: Our thickness gauges come with 7 settings which will cover the most common board thickness found in USA.

  • 1/2'' Inch
  • 5/8'' Inch
  • 3/4'' Inch
  • 7/8'' Inch
  • 1'' Inch
  • 1 1/4'' Inch
  • 1 1/2" Inch

EasyRead Label: The v2 Imperial Thickness Gauge design uses a new highly durable label. The labels have an outer laminate making them scratch resistant under most conditions. We chose white text on a black label which is ideal contrast for reading in almost all lighting conditions.

Detent Design: The thickness gauge uses the same OEM positive detent system that comes with the Festool Domino Joiners. This means you will have the same functionality and feel as the OEM thickness gauge.

Bigger Tab: We made the tab on the side slightly bigger so that it is easy to switch between the thickness settings.

Materials: This is made out of strong PLA plastic and comes in a matching Festool Green or Black.

Great Product

Really prompt shipping. I haven’t been able to check the accuracy of the imperial thickness gauge but expect to have to tweak it manually to account for minor variances in board thickness.
