The Festool Track Saw Dust Bag Conversion Kit, model 500393KIT, is an accessory kit made to convert select Festool track saws for dust collection with the newer Festool dust bag. This is a track saw dust bag conversion kit designed for cleaner cutting when a dust extractor is not convenient to connect. If you already run a compatible TS-series saw and want a more self-contained setup for quick cuts, this kit solves that problem with the correct replacement port and reusable bag.

What matters here is that this is not just a replacement bag. The kit includes a retrofit dust port with the special connector needed for the bag, so the saw can be converted properly instead of patched together with mismatched parts. That makes it useful for users who want a cleaner, more portable cutting setup on installs, punch-list work, or anywhere dragging a hose is more hassle than help.

The bag itself is built for repeat use. An integrated zipper lets you empty collected dust instead of tossing the bag after one use, which helps keep operating costs down and makes cleanup less annoying. When the job is done, the bag collapses flat for storage in a Festool Systainer, so it fits better into a packed van or trailer than a bulky fixed collection setup.

The included replacement dust port also works with standard Festool dust extractor hoses. That gives this kit some flexibility. You can set the saw up for the new dust bag, while still using a standard Festool hose connection when full extractor-based dust collection makes more sense. For users already invested in Festool track saw accessories and dust management, that compatibility is the practical detail that makes this kit worth buying instead of improvising.

Installation is more involved than snapping on an accessory. Festool notes that you will need to remove the blade housing from the saw and swap the original dust port for the one included in the kit. The dust port fitting is keyed, so you may need to rotate the port for proper fit during installation. That is not difficult for a capable user, but it is worth knowing up front if you are expecting a tool-free add-on.

This conversion kit is specifically for users of the Festool TS 55 REQ, TS 55 EQ, or TS 75 EQ who want cleaner cuts without always running a dust extractor hose. It makes the most sense for cabinet installers, finish carpenters, remodelers, and serious DIY users who use a Festool track saw on site and want better dust control with less setup.

A smart add-on for TS-series users who want less hose and less mess
