FF87 80 grit 820 mm x 40 mm is our high performance, ceramic abrasive belt material with a waterproof backing.
With an F weight back, FF87 is more flexible than the FX87 material.
We recommend FF87 where a high cut rate and long belt life are demanded for intermediate grinding.
FF87 abrasive belts are particularly good on stainless steel, steel and aerospace alloys.
