Key Features
Overview
The Festool ETSC 2 150 4,0 I-Plus cordless random orbit sander is a cordless 6 inch finish sander built for surface prep, finish sanding, and defect spotting on wood and painted surfaces. This is a cordless random orbit sander designed for fine sanding, finish work, and surface correction. Model Number: 577728. If your work depends on seeing flaws before the finish goes down, this tool matters because the built-in LED light ring shows you what normal overhead shop lighting can miss.
What separates this sander from a lot of other cordless sanders is that the light is not an afterthought. Festool built the ETSC 2 around visibility as much as sanding performance. The random orbit action is there to leave a clean, consistent surface, but the real advantage is being able to inspect as you go. On cabinet doors, face frames, tabletops, trim, and painted surfaces, that saves time because you are not finding scratches and low spots later under stain, paint, or clear coat.
The 18V platform and included 4.0 Ah batteries make it practical for real work, not just quick touch-ups. You get cordless mobility for sanding in a shop, inside a finished house, or anywhere a cord gets in the way. Festool also designed it to work without a hose when needed by using the included dust bag, which is a real benefit for punch-list sanding, overhead work, and moving from piece to piece without dragging a dust extractor behind you.
From a handling standpoint, the low-profile body is a big deal. Your hand sits close to the pad, which gives you better control on flat stock and better comfort when sanding vertical or overhead surfaces. The brushless EC-TEC motor is built for quiet, efficient operation with less maintenance than a brushed motor, and the vibration protection helps reduce hand fatigue on longer sanding sessions. That matters if you are working through multiple panels or doing finish prep all day.
The sanding pad brake is another feature that earns its keep. Festool uses a carbide-tipped pad brake to keep the pad from free-spinning too aggressively at startup and while idling. In plain terms, that helps prevent the sander from leaving scratches when you set it down on the workpiece. For finish sanding, that is not a small detail. It is the kind of feature that cuts down on avoidable rework.
Speed control is also set up for material changes. The eccentric motion speed ranges from 6,000 to 10,000 RPM, so you can slow the tool down for more delicate finish work or turn it up when you need faster stock removal within the tool's finish-sanding role. Festool notes that it maintains constant power under load, which is useful when you are working across broad surfaces and want a more consistent sanding pattern.
System compatibility is strong here too. The ETSC 2 uses Festool's 18V battery system, so the included batteries and charger fit into the larger cordless platform. Bluetooth connectivity adds another layer of control through the Festool App, letting you adjust the light output more precisely for inspection after sanding. If you are already invested in Festool cordless tools, this sander drops right into that setup without adding another battery platform to manage.
Who should buy it? This is a smart pick for cabinet installers, finish carpenters, woodworkers, painters doing prep, and remodelers who care about surface quality. Serious DIY users will appreciate it too, especially if they are sanding furniture, doors, trim, or built-ins and want a cleaner result with less guesswork. If you mostly do aggressive stock removal, this is not the wrong tool, but it is definitely aimed at finish sanding and surface refinement, where control and visibility matter more than brute force.
See Surface Flaws Before Finish Goes On

The integrated LED light ring is the headline feature for a reason. It throws light directly across the work surface so imperfections show up while you are sanding, which is exactly when you want to catch them.
- Built-in light ring improves visibility on the work surface
- Bluetooth connectivity supports additional light adjustment through the Festool App
- Designed to help spot uneven areas and reduce rework
Stay Mobile Without Fighting a Cord

This setup is built for moving around. When you do not want a hose or extension cord slowing you down, the ETSC 2 gives you genuine cordless finish sanding for shop work, install work, and touch-up sanding in tight spaces.
- 18V battery-powered platform with included 4.0 Ah batteries
- Includes a dust bag for sanding without a mobile dust extractor
- Ships in a Systainer for organized storage and transport
Keep Better Control on Flat and Overhead Work

The low-height design puts your hand closer to the surface, which gives the tool a more planted feel than taller sanders. That helps with control, especially when you are working broad panels, edges, or sanding above shoulder height.
- Low-profile one-handed design for close-to-surface control
- Vibration protection helps reduce fatigue over longer sanding sessions
- Carbide-tipped sanding pad brake helps avoid startup scratches

Pro Tip
Use the light ring as an inspection light, not just a work light. On painted doors, tabletops, or clear-finish pieces, make a final slow pass with the light dimmed through the app or machine settings so scratches and sanding swirls stand out before you call the surface done.

Tool Nut's Take
Festool ETSC 2 150 4,0 I-Plus cordless random orbit sander for finish guys who actually care what the surface looks like
This is the kind of sander that earns its price by helping you catch mistakes early and sand cleaner the first time.
- Who it's for: Finish carpenters, cabinet installers, woodworkers, painters doing prep, and serious DIY users who want a true finish sander, not a rough stock-removal tool.
- Why it stands out: The light ring is not a gimmick. Paired with the low-profile body, brushless motor, and pad brake, it gives you better visibility and better control where surface quality matters most.
- Worth knowing: This is a finish-focused 6 inch random orbit sander. If your main job is heavy material removal, look elsewhere. If your job is making the surface right before finish, this one makes a lot of sense.
