Newer version of this product - DF500 Thickness Gauge v2


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.

  • Changes out metric thickness gauge to imperial measurements for USA woodworkers - 7 settings for common board thickness in USA
  • Measurement indicators are imprinted making them scratch and wear resistant
  • 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

Imprinted Indicators: The indicators are imprinted into the plastic which makes them wear resistant compared to the OEM model.

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.

Pretty nice

My only criticism is that the numbers are hard to read. That's why it didn’t get the fifth star!
