The Festool Depth Position Indicator FS-EP for TS/TSC 55 (item 578695) is a guide rail accessory that marks the precise entry and exit points of the saw blade for plunge cuts. This is a positioning aid designed for plunge-cut track saws, built for cuts where you need to start and stop the blade at an exact mark rather than running a full-length cut. It's a small piece of gear, but it solves a real problem on any job that involves sink cutouts, panel cutouts, or interior cuts that don't run edge to edge.

The indicator sets directly into the guide rail groove and aligns to your cutting depth, so when you plunge the saw, the blade enters and exits exactly where the indicator shows — no guessing, no test cuts, no overcutting past your line. It works as both a front and rear stop on the rail, which means you get consistent, repeatable plunge cuts at both ends of the cut, not just a single reference point. The symmetrical design lets you position it on either side of the guide rail, which matters when you're cutting close to a wall or in a tight space where you can't get a full-length rail extension on both sides.

Setup is tool-free: the indicator drops in from above and locks into the guide rail groove without a wrench or screwdriver, and an adjustable scale lets you fine-tune the calibration to match your specific saw, guide rail, and even a blade that's been resharpened and runs slightly narrower than new. It also displays cutting width directly, which is useful anytime you're laying out narrow panel strips and need an accurate reference without reaching for a spacer block or tape measure.

This accessory is built for the Festool TS 55 R, TS 55 F, TSC 55, TSC 55 K, and TSC 55 KS track saws used with the FS/2 guide rail system. If you're doing sink cutouts, cabinet panel cutouts, or any layout work that calls for accurate start and stop points on a plunge cut, this is a straightforward upgrade over eyeballing your marks through the blade guard. If most of your cuts run edge to edge with no plunge involved, you likely won't get much use out of it.

Small Accessory, Big Difference on Plunge Cuts

The Festool Depth Position Indicator FS-EP takes the guesswork out of starting and stopping a plunge cut exactly where you meant to.

• Who it's for: Anyone doing sink cutouts, panel cutouts, or interior plunge cuts with a TS 55 or TSC 55 track saw who's tired of eyeballing the blade guard to find their marks.
• Why it stands out: It works as both a front and rear stop, mounts on either side of the rail for tight-to-the-wall cuts, and shows cutting width directly — three jobs handled by one simple, tool-free accessory.
• Worth knowing: It's built specifically for the TS 55 R, TS 55 F, TSC 55, TSC 55 K, and TSC 55 KS — it's not a universal guide rail accessory, so confirm your saw model before buying.

• Does this work with any Festool track saw? No. It's designed specifically for the TS 55 R, TS 55 F, TSC 55, TSC 55 K, and TSC 55 KS track saws used with the FS/2 guide rail system.
• Do I need tools to install it? No. It drops into the guide rail groove from above and locks in place by hand.
• Can I use it for cuts close to a wall? Yes. Its symmetrical design lets you mount it on either side of the guide rail, which is what makes it useful for cutouts near walls or in tight spaces.
