FF87 120 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 desired for fine grinding.
FF87 abrasive belts are particularly good on stainless steel, steel and aerospace alloys.
Use the P120 grit belts for scratch removal and pre-finishing before the use of surface conditioning belts.
