JF4top 180 grit 1065mm x 25mm 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 finishing and polishing anything from stainless steel to brass.
For belt size 1065 x 25mm we recommend you use the JF4top 180 grit belt when you have a slack of belt application. If you wish to work against a platen then the HA66/180/1065X25 will give much better performance.
We particularly recommend JF4top for flexible belt applications (such as the Finitube or Beltit powerfiles) on stainless steel and non-ferrous metals.
