The RTS-500 Cutter Adapter is a precision machined, hardened steel component that allows mounting any of the Festool Domino DF 500 cutters to the Festool Domino XL DF 700. This enables the DF 700 to cut smaller mortises that previously could only be done with the DF 500. Any of the standard Domino Cutter bits (4mm/5mm/6mm/8mm/10mm) will work with this adapter.
The RTS-500 Cutter Adapter is sized so that when attached to a DF 500 cutter, the overall length is the same as a DF 700 cutter. This ensures mortises cut with DF 500 cutters on the DF 700 are the same width as they would be if cut with the DF 500. This also maintains the accuracy of the plunge depth gauge on the DF 700 and simplifies setting mortise depth.
In addition to the RTS-500 adapter, you may want to check out our Imperial Thickness Gauge + Domishim set which allows the Domino XL DF700 to center on ply much narrower than it was originally designed for.
