Just bits, clamps and systainer -- rail not included.
EDIT: I don't do production level cabinetry, and I have the clamps already, so I found it more economical to get the basic set, add in the 5mm bits as separate buys, and then do the hinge boring with CMT metric forstner bits. Keep in mind too that there are cheaper alternatives for the 5mm self-centering hinge bit made by Festool that you might need to drill the center holes for things like drawer slides.
