Festool 497304 Carvex Jigsaw Circle Cutter, Metric is a circle cutter accessory for Festool CARVEX jigsaws. This is a circle cutter accessory designed for precise circle and arc cuts. Model Number 497304. If you need cleaner, more controlled round cutouts than freehand jigsaw work usually delivers, this is the add-on that makes the tool behave more like a guided cutting system than a guess-and-correct setup.

The big reason this accessory matters is simple: consistent radius. It extends for cuts from 4-3/4" (120 mm) up to 9.8 ft (3 m) in diameter, which gives you a useful spread from smaller cutouts to large arcs. On the job, that means one setup can handle a lot of layout work without cobbling together shop-made trammels or trying to pivot the saw by eye.

Festool designed it to work with the CARVEX platform, and it attaches tool-free to the required Base Adapter 497303. That is a practical detail, not just a convenience feature. If you are switching between regular jigsaw cutting and circle cutting, fast attachment keeps the workflow moving and makes the accessory more likely to be used instead of left in the case.

The design is straightforward and jobsite friendly. The adjustable arm gives you a measurable radius reference, and the compact roll-up storage makes more sense than a long rigid jig that is awkward to pack. For anyone who wants accurate repeatability without carrying a bulky homemade fixture, that compact storage is a real plus.

Compatibility is the key buying point here. Festool lists it for PS(C) 420 and PSB(C) 420, and states that it works with all Festool CARVEX jigsaw models when used with the adapter table ADT-PS 400 / Base Adapter 497303. If you already run a CARVEX jigsaw and occasionally need circles, speaker openings, rounded panels, or controlled arc cuts, this accessory fits that use case cleanly.

This is best for woodworkers, finish carpenters, cabinet installers, and serious DIY users who already own a Festool CARVEX and want a more precise way to cut circles. If you do not have the required base adapter, factor that in before you buy. But if you do, this is a much cleaner solution than improvising every time a radius cut comes up.
