150-grit diamond coating
The abrasive surface is designed to cut common nut and saddle materials while polishing the slot.

Independent shopping perspective
Use this .105 in. nut file for focused nut or saddle slot adjustment. Its 150-grit, industrial-grade diamond coating works on nylon, bone, graphite, and TUSQ, while the rounded blade follows a string-shaped profile. The file cuts and polishes the slot together and is designed to stay on course rather than drift like common toothed files. An ergonomic handle supports controlled, comfortable work on electric, acoustic, and classical guitars or 5-string basses.
