The Festool 577048 Corded RENOFIX RG 130 ECI-Plus Surface Restoration Grinder Set is a corded surface-restoration grinder built for aggressive material removal on renovation jobs. This is a surface-restoration grinder designed for removing concrete, screed, coatings, and adhesive residue from tough subsurfaces. Model Number 577048. If your work starts with getting a floor, wall, or ceiling back to a clean, usable base, this is the kind of tool that saves time where lighter grinders start tapping out.

The big story here is the brushless EC-TEC motor. Festool rates it at 1,600 watts, and more important than the number itself is what it does in practice: it keeps removal rates up without constant overheating or shutdowns. On jobs where you are stripping old coatings or cleaning up concrete before the next phase, that steady output matters more than flashy specs. The variable speed range of 2,200 to 6,500 RPM also gives this grinder some range, so you can back it down for better control or turn it up when the material and wheel call for faster stock removal.

Festool also built this grinder around control, not just raw removal. The guide table helps you keep the tool steady and lets you adjust removal height, which matters when you want consistent results instead of gouging the surface. The brush segment lets you work right up to a wall edge, which is a real advantage in room prep and perimeter cleanup where bulky shrouds often leave unfinished strips. That makes the RG 130 ECI-Plus a practical choice for remodeling crews, flooring contractors, and concrete prep work where edge access can make or break how much handwork is left at the end.

Dust handling is a major part of why this tool stands out. Festool specifically calls out strong extraction performance when the RG 130 ECI is paired with CT 36 AC HEPA or CT 48 AC dust extractors, and other product data also references the CTM 36 AC RENOFIX extractor. For indoor renovation, that is not a side benefit. Grinding concrete and old coatings creates fine dust fast, and a grinder that works well with a dust extractor helps keep the air clearer, the cut line more visible, and cleanup under control. The 36 mm dust port connection is built for that setup.

There are some smart jobsite details too. The tool runs on 120 VAC power, so you get continuous runtime instead of planning around batteries on long prep jobs. Festool also notes Bluetooth connection functionality that can automatically start a connected extractor in certain setups, which helps streamline workflow when you are moving room to room. The cable is just over 13 feet long, giving you decent reach before you need an extension cord. At 8.59 pounds, it is not a featherweight, but for a 130 mm grinder made to remove material aggressively, that weight works with the tool rather than against it by helping it stay planted.

The 130 mm tool diameter and D25/M14 tool holder point to a grinder made for purpose-built surface prep accessories, not general cutoff work. That matters because this is not trying to be an all-purpose angle grinder. It is a dedicated concrete and coating removal tool. If your work regularly involves substrate preparation before overlays, flooring, adhesives, or finish materials go down, a dedicated machine like this will usually do the job faster, flatter, and cleaner than trying to force a standard grinder into a job it was not designed for.

Who should buy it? Contractors handling renovation and remodeling, flooring prep, coating removal, concrete surface cleanup, and selective grinding on walls, ceilings, or floors are the best fit. Serious users who already run Festool dust extraction will get even more out of it. If you just need a grinder for occasional light-duty work, this is probably more tool than you need. If substrate prep is part of how you make money, the Festool 577048 Corded RENOFIX RG 130 ECI-Plus Surface Restoration Grinder Set is built for exactly that kind of work.
