Thread: Dura Grit Tru Sander Blocks

I bought mine direct - prices and postage were reasonable if you got enough. Did take a while to arrive though - small operation I believe, so stock can take a while to replenish.

Thanks for that, I did find a NZ supplier but it worked out slightly more expensive (Aveteknz <[email protected]>). Still a little unsure of the grit sizes, Avetek in NZ had a 80 and 120 grit discs but Dura Grit in US only maufacture 46, 60 or 80 grit discs. Am I missing something or do the US have a different grit system

There are 2 FEPA scales: The P scale is for papers and the F scale is for stones/wheels. Since the tru sander is more like a stone they may well be using the F scale. F46 is between P40 and P50, F60 = P60 and F80 is between P80 and P100.
