I have a couple of MFTs, but want to make some smaller work tables for sanding and other odds and ends. That will help keep my MFTs clear from the junk. I'll be using the LR32 kit to make some smaller tops. What's the best Festool router bit to use in order to make the 20MM holes? I now have the 1400 and 1010, so shank size is not an issue. Thanks in advance.
