The Festool Cordless 18V ETSC 2 125mm (5-in.) Sander Kit w/ 60-Piece GRANAT Abrasive Starter Pack is a cordless finish sander kit built for clean surface prep, finish sanding, and touch-up work where control matters more than brute force. This is a cordless finish sander designed for surface prep and fine sanding on wood, filler, varnish, and other hard substrates. Model numbers in this bundle are 577738 and 578668.

What separates this kit from a basic cordless sander is the way it helps you see your work while you sand. The integrated LED light ring throws light directly across the surface so uneven areas stand out sooner. That matters on painted panels, clear-finish hardwood, patch work, and final prep before topcoat, where missed scratch marks turn into callbacks.

The low-profile body keeps your hand close to the workpiece, which gives better feel and control than taller sanders, especially on narrow parts, edges, vertical panels, and overhead sanding. Festool also pairs that compact shape with vibration protection, so the tool is easier to run longer without beating up your hands. If you spend real time sanding cabinets, trim, doors, or built-ins, that is not a small thing.

The brushless EC-TEC motor is built for steady performance with less maintenance than a brushed motor. Festool calls out that it is robust, powerful, and particularly quiet. On the job, that means a sander that is meant to keep up with daily finish work without the extra service concerns that come with older motor designs.

Festool also added a carbide-tipped sanding pad brake to keep the pad from spinning too fast at idle. That helps reduce the chance of setting the tool down on the surface and leaving unwanted swirl marks or scratches. If you do finish sanding for a living, that feature pays off fast because it protects the workpiece and cuts down on rework.

This kit includes a 4.0 Ah battery setup and works within the Festool 18V cordless system, so batteries and chargers can be shared across compatible Festool 18V tools. The machine also offers two onboard light modes, full and dimmed, and the light can be adjusted more precisely through the Festool app. That gives you more control when you want bright task lighting during sanding or softer raking light for a final surface check.

The included D125 GRANAT abrasive starter set gives you 60 sanding discs across six grit levels: 60, 80, 120, 180, 220, and 320. That is a smart range for moving from heavier material removal into finish-ready sanding without piecing together assortments on your own. Festool notes these discs are especially well suited to VOC varnishes and hard substrates, and the special hole pattern is designed to reduce clogging for cleaner, more dust-conscious sanding.

Who is this kit for? Cabinet installers, finish carpenters, woodworkers, remodelers, painters doing prep, and serious DIY users who care about surface quality. If your work ends with stain, paint, clear coat, or visible trim, the Festool Cordless 18V ETSC 2 125mm (5-in.) Sander Kit w/ 60-Piece GRANAT Abrasive Starter Pack makes a strong case because it is built around control, visibility, and finish quality, not just sanding speed.
