It's time to re-stock paper for my sander. I was looking at various sites and came across something puzzling on Klingspor's site. It seems they have a Good-Better-Best offerings. The cheapest one - Klingspor Abrasives Shop Roll, 3"x 50Yds, 80 Grit, J-Flex Cloth Backed Aluminum Oxide has a disclaimer that it is not recommended for drum sanders. Their next offering - Klingspor Abrasives 3" x 50MT 80 Grit Premium Aluminum Oxide Drum Sander Rolls is $24 more for the same 50 yd roll and the only difference seems to be the backing.
When I replace paper on my sander it's always because the grit on the paper is worn away and/or clogged up after a couple of cleanings with SimpleGreen. The backing has never been an issue.
Am I missing something here? What do you use?
