Jf4top 220 grit 610mm x 40mm is a very flexible, high purity aluminium oxide abrasive material with additional grinding aids in the top coating.
JF4top has a great belt life when used for finishing and polishing of anything from stainless steel to brass.
Use this belt for fine grinding.
We particularly recommend JF4top for flexible belt applications (such as the Finitube or Beltit powerfiles) on stainless steel and non-ferrous metals
