Key Features
LED Light RingThe integrated light ring lets you see scratches, swirl marks, and uneven spots while you sand, not after finish goes on. That means less guesswork and less rework. Low-Profile ControlThis Festool cordless random orbit sander sits low in the hand, so you can stay closer to the surface and keep better control on flats, edges, and overhead work. Brushless EfficiencyThe EC-TEC brushless motor delivers steady sanding power with less noise and less maintenance. That matters when you use a sander often and want consistent results.
Overview
The Festool ETSC 2 125-Basic cordless random orbit sander, Model 577735, is a compact 18V finish sander built for surface prep, finish sanding, and defect spotting on woodwork. This is a cordless random orbit sander designed for fine sanding and surface finishing. If you work on cabinetry, furniture, doors, trim, or site touch-up work, this tool is aimed squarely at clean finish quality without being tied to a cord.
What makes this sander different is the integrated LED light ring around the pad. That is not a gimmick. It throws light right across the surface so uneven areas, scratches, and sanding defects stand out while you are working. Combined with the random orbit motion, it helps you catch problems early and reduce rework before stain, paint, or clear coat makes them more obvious and more expensive to fix.
The low-profile body is another big deal here. Festool designed the ETSC 2 125-Basic to sit close to the work so your hand stays near the sanding surface. In real use, that gives you better feel and better control, especially on edges, narrow parts, face frames, door panels, stair parts, and overhead sanding. At 2.65 lbs, it stays light enough for extended use without feeling toy-like.
Power comes from Festool’s 18V battery platform, and the sander is driven by a brushless EC-TEC motor. The speed range of 6,000 to 10,000 RPM gives you room to match the cut rate to the material and the stage of sanding. Faster settings help with efficient stock removal in the finish-sanding range, while lower settings give you more control on sensitive surfaces or finer grits. Festool also calls out constant power under load, which matters when you want the tool to keep cutting evenly instead of bogging down as pressure changes.
Festool also built in a sanding pad brake with carbide-tipped components to keep the pad from overspinning at startup or free spinning when it is not planted on the work. In plain terms, that helps prevent the kind of sudden contact marks and surface scratches that can show up when a pad is moving faster than it should be. Add in built-in vibration protection, and the tool is set up to stay comfortable through longer sanding sessions.
For dust control and jobsite practicality, the Festool ETSC 2 125-Basic can run with its included dust bag when you want maximum freedom of movement and do not want a hose dragging around the work. It also uses a 27 mm dust extraction connection if you want to tie into Festool dust extraction. That makes it flexible for both shop sanding and punch-list work where portability matters more than full extractor setup.
Pad size is 5 in. with a 125 mm interchangeable sanding pad diameter and a 9/64 in. sanding stroke. That puts it in the sweet spot for finish sanding on flat surfaces, trim, doors, tables, casework, steps, cladding, fences, balcony boards, and spot repairs. It is not trying to be a heavy stock removal machine. It is a detail-conscious finish sander for users who care what the surface looks like when the work is done.
If you already run Festool 18V cordless tools, the battery compatibility is a real advantage because you can swap packs and chargers across the platform. Since this is the Basic version, it is a bare tool setup with no battery or charger included. That makes the most sense for current Festool users, finish carpenters, cabinet installers, remodelers, woodworkers, and painters who want cordless mobility, strong dust control options, and a better view of the surface while sanding.

The built-in LED ring is the feature most people will remember after using this sander once. Instead of moving the workpiece around to chase glare and spot scratches, the light is already where you need it.
- Integrated LED light ring improves visibility during finish sanding
- Multiple light settings are available, with additional light adjustment through the Festool App
Work Freely Without Fighting a Cord
On chairs, trim, stair parts, and installed work, cords and hoses can be more annoying than the sanding itself. This cordless setup gives you better movement when you are changing angles or working in awkward positions.
- 18V battery platform shares packs and chargers across Festool cordless tools
- Included long-life dust bag supports hose-free sanding when mobility matters most
Keep Control on Flat Surfaces and Overhead Work
The body shape stays low and close to the pad, which helps the tool feel planted instead of tippy. That is especially useful when you are trying to keep even contact on broad panels or working above shoulder height.
- Low-profile design improves hand position near the sanding surface
- Tool weight is 2.65 lbs for lighter handling during extended sanding sessions
Match the Abrasive to the Job
A finish sander is only as useful as its pad control and abrasive setup. The 5 inch pad size is a common, practical format for surface prep, and the variable speed range helps you tune the cut to the material and grit.
- 5 in. interchangeable sanding pad diameter handles common finish sanding tasks
- 6,000 to 10,000 RPM speed range helps balance cut rate and surface quality

Pro Tip
Use the LED ring after your final grit pass and change your viewing angle before calling the surface done. That light will show scratch patterns and uneven sanding that normal overhead shop lighting can hide.
