So S4000 is a silicon carbide P4000 grit abrasive. This grit size is not on Festool's chart probably since grits finer than P2500 are not standardized and the micron size can vary based on the manufacturer. The easiest solution I can think of is to use this block for grits up to P4000/1500 grit, and a traditional sanding block for 2000 grit if it's necessary. Ah, ok, it makes sense now.

See page #3 in the above link for their range of both silicon carbide and aluminum oxide abrasives. Also, take note of the foam fiber backing for the S4000. Call them and request a sample. Hope this helps......Jim Stuart,

If it's a FEPA grit standard, then it's approximately 1500 grit, but then again it would then be designated P4000 as opposed to S4000. Maybe it's a Japanese standard grit, but then again why would a German company be using JIS standards? Almost all searches for "S4000 abrasive" results in a Festool product mention. Jim,

The finer grits are often used for solid surface work. See http://www.festoolusa.com/ProductDetails.aspx?ProdID=492372&ID=7 Festool carries 6″ H&L up to S4000, althought it does have holes.

The discs, being plastic-backed, might not be flexible enough to be securely bent and fastened to the sides of the block.

Although I too have had difficulty sourcing these grits in anything other than sheet form, I think McMaster has something compatible. Head over to www.mcmaster.com, and search for item # 4321A35. These are plastic-backed discs, so the cost is higher. Also, although the package size is 50 discs, you can order a fraction of a package, albeit at a 20% penalty charge. Rick,

I've seen it in 80, 220, etc. Was there something unique in the hook and loop that you were looking for? Here's a bit of a selection from a quick amazon search: http://tinyurl.com/37ru92 Evan,

I've only seen the real fine color-sanding grits (1500 and up) available in sheets. Can you even wet sand with hook and loop backed paper? I use the hand sanding blocks for wet sanding. Granted, sanding down the skim coat of Bondo uses grittier paper in which case this would probably work pretty good. What are the different grits available in 6″ hook and loop?
