Description

MusicNomad MN657 Diamond-Coated Nut File – .036" / 0.91 mm

The MusicNomad MN657 nut file, with a diameter of 0.91 mm (0.036"), is part of the premium series of diamond-coated nut files and is ideal for precise notching work on guitar or bass nuts. Whether you’re filing new slots or optimizing existing ones, this file ensures clean, smooth results without the typical “chipping” or chatter of conventional files.

The patent-pending “String-Shape” blade is perfectly matched to the curvature of the strings. This creates a precise fit for the string, which directly affects intonation, playability, and sustain. At the same time, the notch is automatically polished during filing—a huge advantage for anyone aiming for a professional setup.

For guitar builders, technicians, and anyone who values precision

Thanks to its uniform, industrial-grade diamond coating, the MN657 is ideal for materials such as nylon, bone, graphite, plastic, or TUSQ. Even bridge saddles made of brass or zinc can be worked on with ease—making this file exceptionally versatile. From electric guitars and acoustic guitars to classical instruments and 5-string basses, it covers a wide range of applications.

The ergonomic handle ensures comfort during longer work sessions and precise control. The blade is removable and can be used separately—perfect for individual work styles. A laser-engraved size marking on the blade also provides clarity and prevents mix-ups in your tool collection. An integrated hole in the handle allows for space-saving storage by hanging it directly on the workbench.
