Abrasive, waterproof paper rolls mounted on a 3/32" shank.
They are perfect for filing, sanding and cleanup work. The wrapped paper is bonded with a glue at the bottom so the paper stays wrapped until you are ready to expose a fresh layer of abrasive paper.
The paper roll is approximately 12mm in diameter and 30mm long. The overall length including the shank is about 57mm (2-1/4").
Sold in a pack of 3.
