Sanding Belts - 400 Grit 3'''' (7.6cm) X 25 7/32'''' (64cm)

About "Compact Grain" Belts - Aluminum Oxide Belts in super-fine grit (like 600) are only available in what the maker calls "Compact Grain". This process layers grit in a special adhesive and greatly increases belt life. Compact grain belts are easily identified; they are ugly! The 600 grit belt shown looks like it should be a 60 grit but IT ISN'T. It really will give a 600 grit finish and will last extremely well. Resin bonded, aluminum oxide. Sold singly.
