I used Festool for quite a while. They offer a variety of abrasive media, but I would point out that Festool- a fantastic, German-built tool- markets their products to all skills and trades requiring abrasives, including automotive and any other kind of finishing and re-finishing skills. My needs are almost exclusively varnishing. For that, I have used Klingspor discs. Klingspor compares favorably to Festool Platin, and much cheaper. For the final Steinway piano-like polishing I have switched to 2000 and 4000 grit Abralon pads by Mirka, also equal to Festool. Regarding quality- Festool is expensive with great customer support. I have spent on Festool equal amounts to what I have spent on Ryobi and DeWalt over the years. I have a lot of exterior teak
, and I have gone through a fair number of sanders over the years. Besides features such as variable speed and random orbit, they all do the about the same job. Festool has a comprehensive system including their dust “ extractor” that will have little benefit if one mostly works outside. Over time, and depending on how much work
you do, you will spend about the same on the tools, whether Harbor Freight, Ryobi, or Festool.
