The Festool 576790 CARVEX Accessory Kit w/ Systainer3 is a jigsaw accessory kit built for Festool PS 420 CARVEX users who want to get more out of the saw they already own. This is a jigsaw accessory kit designed for expanding cutting capability, improving cut quality, and making the PS 420 more adaptable on the job. Model Number: 576790.

Instead of buying individual add-ons one at a time, this kit puts the full CARVEX base system together in one package. You get multiple bases and base inserts, plus the angle base, guide rail base, circle cutter, and splinterguards. In practical terms, that means one jigsaw can be set up for finish-sensitive cuts, guided straight cuts, angle work, metal-cutting support, and radius work without piecing the system together later.

The real value here is not just the number of parts. It is how quickly the kit changes what the jigsaw can do. The angle base is the one many users end up reaching for when trim, fit-out, or detail work needs controlled bevel or angled cutting support. The circle cutter matters when you need repeatable arcs, radii, or round cutouts without laying everything out by hand and hoping the blade tracks cleanly. This version includes the imperial rule on the circle cutter, which is useful for users who work in inch-based layouts.

Festool also includes splinterguards for tear-free cuts, which is a big deal when the workpiece is already finished or close to finished. On sheet goods, veneered panels, or visible trim materials, cleaner top-edge results can save sanding, touch-up, and callbacks. The guide rail base adds another level of control for straight work where freehand jigsaw cuts are not good enough.

From a system standpoint, this kit is built around the Festool CARVEX platform. It is compatible with all Festool CARVEX jigsaw models, and the accessory list is centered on the PS 420 family. That makes it a strong fit for users already invested in the tool and looking to unlock more applications from the same saw rather than jumping to another specialty tool right away.

The included Systainer3 is not just packaging. It keeps the full accessory set together, protected, and easy to grab for install work, shop work, or punch-list jobs. If you use the CARVEX regularly, having the right base, insert, and specialty accessory organized in one case saves real time and cuts down on missing parts.

This accessory kit makes the most sense for finish carpenters, cabinet installers, remodelers, and woodworkers who already own a Festool CARVEX jigsaw and want more precision and flexibility. It is also a smart buy for anyone doing varied jigsaw work where cleaner cuts, guided cuts, and specialty shapes come up often enough that the accessories pay for themselves in time saved.

Festool 576790 CARVEX Accessory Kit is the one to buy if you actually use your jigsaw for more than rough cuts

This kit takes a good CARVEX and turns it into a much more versatile cutting system without forcing you to hunt down every specialty base one at a time.
