The Festool Cordless 18V ETSC 2 125mm (5-in.) Sander w/ 100-Piece GRANAT Abrasive Systainer Set is a cordless finish sanding setup built for woodworkers, cabinet installers, finish carpenters, and anyone who cares what the surface looks like when the job is done. This is a cordless eccentric sander designed for finish sanding and surface prep. Model Number: ETSC 2 125. What makes it different is simple: it gives you the freedom of cordless sanding, a low-profile one-hand grip, and an integrated light ring that helps you actually see flaws while you work.

Festool built this sander around control, not just power. The low height lets your hand stay close to the work surface, which matters when you are sanding edges, face frames, stair parts, and overhead panels where a taller tool can feel top-heavy. The eccentric sanding motion is there to produce strong surface quality while reducing the kind of visible sanding mistakes that lead to extra prep and rework. Festool also calls out a carbide-tipped sanding pad brake, which helps keep the pad from free-spinning too fast at idle. In practical terms, that means cleaner starts when you set the tool down on the work instead of leaving random scuffs or scratches.

The integrated LED light ring is one of the standout features here because it solves a real problem on fine sanding work. Under normal room light, it is easy to miss low spots, leftover machine marks, or inconsistent scratch patterns until stain or clear coat goes on. The light ring gives you a better read on the surface as you move, and the tool offers two light modes on the machine itself. Festool also notes that light adjustment can be customized through the Festool app, which gives you another way to dial in inspection lighting when you are chasing a finish-ready surface.

Under the hood, Festool uses its brushless EC-TEC motor. That matters because brushless tools generally run with less maintenance and better efficiency over time, and Festool specifically describes this one as robust, quiet, and low-maintenance. The sander also features vibration protection to reduce hand fatigue during longer sanding sessions. If you spend a lot of time on doors, panels, trim, or built-ins, that kind of comfort feature is not fluff. It is the difference between staying consistent through the last piece and rushing the final passes because your hand is cooked.

As part of Festool's 18V cordless system, the ETSC 2 125 is designed to work with Festool 18V batteries and chargers. That is important if you are already on the platform and want to keep packs moving between tools instead of dedicating a battery to a single machine. The product copy specifically references a 4.0 Ah battery for fast work progress, though this listing is described as tool only alongside the abrasive set, so battery and charger inclusion should be confirmed from the listed contents rather than assumed. On the abrasive side, the included GRANAT D125 assortment covers grit sizes from P60 through P220, which gives you a practical range for material removal, intermediate smoothing, and final prep before finish.

The included abrasive Systainer adds real value beyond just storage. It keeps the discs protected from dust, spray, and bending, and it keeps the grits separated so you are not wasting time digging for the right disc. Festool also states that the Systainer can connect with previous Systainer generations as well as many Festool machines and accessories, which is a big plus if your shop or van is already set up around that system. The GRANAT discs themselves are described as especially well suited for VOC varnishes and hard substrates, with a coating that helps resist clogging for longer usable life.

If your work is mostly rough stock flattening or aggressive material removal, this is probably not the first sander you grab. But if your work ends with visible wood, painted trim, finished panels, or surfaces that need to pass a close inspection, this setup makes a lot of sense. It is especially well suited for furniture work, built-ins, stair parts, punch-list sanding, and sanding in tight or overhead positions where cord management gets old fast. For users who want a cleaner, more controlled finish sanding tool with a smart abrasive assortment right out of the gate, this is a well-thought-out Festool setup.
