Nothing if all of the bits that come with the plate are included. In "Festool terms" it's actually a reasonably cheap and useful accessory! I actually grabbed a Trion to dedicate to the plate but it is a very job to install and remove.
there isnt much that comes with it. A black plastic pice that fits on the saw to help with the dust collection and it attaches to the plate by 2 strong backs with knobs.
