The kit includes our RTS-500 Cutter Adapter for using DF500 cutters on your DF700, along with our 10mm "Domi-Shim™".
The Seneca Woodworking 10mm Domi-Shim™ is a machined aluminum shim that attaches to the fence on the Festool Domino XL DF 700 and allows centering on narrower stock than was previously possible. This shim allows the Domino XL fence to adjust all the way to the cutter centerline, allowing centering on material thinner than the Domino XL fence's lower travel limit would previously allow. This shim is an exact 10mm in thickness, designed for use with the METRIC fence height gauge that comes with the Domino XL. When installed, simply subtract 10mm from the reading on the gauge to find the actual fence offset.
