MusicNomad MN658 Diamond Coated Nut File - .042” - Diamond Coated File - 1pc

This patented file features grinding blades with a special industrial diamond coating that accurately replicates the actual shape of the string.

This ensures truly easy grinding and precise grooves that no longer require final polishing. The file is suitable for all traditional materials such as nylon, plastic, bone, graphite, and TUSQ, but can also be used for sanding bridge saddles. The blade of the file is set in an ergonomic handle, which can be easily removed when necessary.
