Do you want to use DF-500 cutters (4mm, 5mm, 6mm, 8mm, 10mm) on your DF-700 XL domino machine?
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 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. Domino depth is however limited by the cutters themselves, so max. 28mm for 5-10mm cutters, and 20mm for the 4mm cutter.
