The Festool D125 GR-Set 5 Inch Multi-Grit Sanding Disc Starter Set is a 60-piece abrasive assortment built around Festool's GRANAT sanding discs. This is a sanding disc starter set designed for finish sanding, surface prep, and step-by-step material removal on paint, filler, varnish, plastics, and other hard substrates. Model Number: 578668. If you run a 5 inch Festool sander and want a practical spread of grits in one box, this set saves you from buying six separate packs just to get started.

What matters here is range. You get 10 discs each in P60, P80, P120, P180, P220, and P320. That covers the full progression from heavier stock removal and shaping through intermediate smoothing and into finer prep before finish work. For painters, finish carpenters, cabinet installers, and shop users doing repair work, that means you can work through a complete sanding sequence without stopping to hunt for the next grit.

Festool positions these GRANAT abrasives for modern paint systems, VOC clear coats, hard sublayers, repair compounds, fillers, acrylic, plastics, and mineral materials. That is important because not every sanding disc handles coated surfaces the same way. The GRANAT line is specifically aimed at finish-sensitive work where loading and inconsistent scratch patterns can slow you down or force rework. If you are sanding fillers, leveling primer, or refining between coats, the disc choice matters just as much as the sander.

The special coating and hole pattern are not throwaway details. The coating is there to help reduce clogging, which extends disc life and keeps the abrasive cutting instead of skating over a loaded surface. The hole pattern supports effective dust extraction, which helps keep the work area cleaner and the abrasive face clearer. On painted surfaces and fillers, that usually means a more consistent finish and less chance of dragging debris across the surface.

From a jobsite and shop standpoint, this set is also just easier to live with than a pile of loose sleeves. The starter-box format keeps the grits organized, lets you pull what you need, and makes it easier to test the full range before committing to bulk quantities of your most-used grits. For anyone dialing in a sanding process on a new material or finish system, that is a smart way to buy.

Compatibility is centered around Festool's 125 mm platform. Festool lists this set for ES 125, ETS 125, ETSC 125, ETSC 2 125, and ETS EC 125 sanders. Supplementary compatibility data also references RO 125, ES-ETS 125, ES-ETSC 125, and LEX 125. Either way, the core point is simple: this is a 5 inch D125 disc set meant for Festool sanders that use that pad size and extraction pattern.

Who should buy it? If you already own a compatible Festool sander and do painted surfaces, clear coats, fillers, acrylic, plastics, or general finish prep, this set makes a lot of sense. It is especially useful for painters and finishers who need a grit ladder ready to go, and for woodworkers who want a clean way to try Festool GRANAT abrasives across coarse-to-fine stages before stocking up on individual grits.
