[Machine Translation] Diamond file with a specially shaped tip. It enables polishing work in deep places that are difficult to reach with a conventional stick file. Also, unlike ordinary steel files, diamond files do not have a file grain (polishing direction). It can be moved freely like a sandpaper, which is useful for polishing work on small areas. *When using "water polishing", the diamonds on the surface may easily peel off and the life of the product may be shortened. The cutting feel of a diamond file and general sandpaper may differ depending on the object to be ground or the work to be performed, even if they are of the same grit size. Tip: Round (ring shape) / Grit size: #140 *The product image is a prototype or an image. The product image may differ slightly from the actual product.
