This base can be used to adapt your Carvex jigsaw to a Festool FS Guide Rail to get extremely straight cuts. When used with the Carvex, it can be attached to a guide rail to cut in either direction.
It is also used in conjunction with the optional circle cutter to cut arcs and circles (#201184/Imperial or #497304/Metric).
Works with all Festool Carvex Jigsaw models.
