The RTS-500 Cutter Adapter is sized so that when attached to a DF500 cutter, the overall length is the same as a DF700 cutter. This ensures mortises cut with DF500 cutters on the DF700 are the same width as they would be if cut with the DF500. This also maintains the accuracy of the plunge depth gauge on the DF700 and doesn’t require any additional math to calculate depth.
In addition to the RTS-500 adapter, you may want to check out our Domi-Shims, which allow the Domino XL DF700 to center on ply much narrower than it was originally designed for.
