Our take on the MusicNomad MN668 6 pc. Diamond Coated Electric Guitar Nut Slotting File Set - Light Strings, with Storage Case

The MusicNomad MN668 is a six-piece nut slotting file set for electric guitars strung with light gauges. Each blade is round and diamond coated, so it cuts and polishes the slot in one pass and resists drifting the way toothed files can. The coating works on bone, nylon, graphite and TUSQ, and the blades also handle saddles. The ergonomic handles can be removed for a shorter cutting option, and the set ships in a compact aluminum case with laser-engraved sizes. It suits players and techs who cut their own nuts and want a controlled, low-drift cut without a full luthier file collection.

MusicNomad’s patent pending Nut Files feature a revolutionary diamond coating & round “string-shape” blade design resulting in smooth, precision cuts. They cut & polish slots at the same time & do not drift like common toothed files. The industrial, even diamond coating cuts & polishes all the most common nut materials such as nylon, bone, graphite & TUSQ. They even work amazing on saddles. We added an ergonomic handle for total comfort & control of your cut, or you can remove the blade from the handle as an alternative cutting option.

Questions and answers

What string gauges does this set cover?
It is sized for light electric guitar strings. The six blades cover the common light-gauge slots; heavier sets need additional sizes.
Will it cut bone and TUSQ nuts?
Yes. The diamond coating is made for bone, nylon, graphite and TUSQ, and it also works on saddles.
Can I use the blades without the handles?
Yes. Each blade pulls out of its handle so you can cut with the bare blade for a shorter reach.
Does it come with a case?
Yes. The set ships in a compact aluminum case with a hang hole and labeled slots for the blades.
Is this the full 16-piece set?
No. This is the six-piece light-string set; MusicNomad also sells a larger set covering more sizes.
Do I need to polish the slot after filing?
Usually not. The diamond coating cuts and polishes at the same time, so most slots are ready after filing.
