FF87 60 grit 675 mm x 40 mm is a our high performance ceramic / al. oxide abrasive belt material with a waterproof backing.
FF87 is more flexible than the FX87 material which makes it really suitable for grinding and finishing bent tubes.
We recommend FF87 where high pressure / high volume stock removal is required on stainless steel, steel and aerospace alloys.
For intermediate grinding.
FF87 performs really well on wide belt sanders for graining stainless steel, on backstand grinders for stainless steel and high pressure steel applcations and also on the Garboli through feed tube grinders and polishers.
