How to Use Hook and Loop Discs on Festool Sanders

Quick answer

Hook and loop (H&L) sanding discs attach directly to Festool-style sanders without adhesive or clamps. The key is matching the disc's hole pattern to your sander's dust extraction and choosing the right grit for each sanding stage.

How to use hook and loop discs on a Festool sander

1. Check disc compatibility: Confirm the disc is 5" diameter with a 9‑hole pattern. Place the disc on the pad without pressing – the holes should align with the pad's dust ports. If they don't, dust won't be extracted and the pad may clog. Never force a non‑matching disc onto the pad; it will block dust flow and reduce performance.
2. Press the disc onto the pad: With the sander off, align the disc's holes with the pad's holes and press firmly from the center outward. The hook‑and‑loop backing grips instantly. A common mistake is pressing only the edges, which leaves air pockets that cause the disc to lift during use. Press from the center outward to remove trapped air and ensure full adhesion.
3. Select the correct grit for the job: Use 80–100 grit for heavy material removal or stripping old finish, 120–180 grit for general smoothing, and 220–400 grit for final finishing. Skipping grits (e.g., jumping from 80 to 220) leaves visible scratches that require extra work to remove. Follow a progressive grit sequence – don't skip more than one grit step at a time.
4. Sand with light, even pressure: Let the sander's weight do the work. Pressing down hard slows the disc and can overheat the hook‑and‑loop backing, causing premature wear. Move the sander in overlapping passes, keeping it flat to avoid gouging. If the sander bogs down or the disc stops spinning, you're pressing too hard.
5. Remove and replace the disc: When the disc loads up or loses its cut, peel it off starting from one edge. Hook‑and‑loop discs release cleanly without adhesive residue. A common mistake is reusing a worn disc – once the abrasive is dull, replacement is faster than forcing a spent disc. Replace the disc as soon as you notice slower cutting or burn marks on the workpiece.

Product facts
