Music Nomad MN670 Diamond Coated 6 Pce Nut File Set 

The Music Nomad MN670 Diamond Coated 6-Piece Nut File Set – Acoustic Light/Medium is a proper bit of kit for anyone serious about getting their acoustic guitar playing exactly right. This isn’t a rough-and-ready solution — it’s all about precision, control, and clean results.

Designed specifically for light to medium acoustic string gauges, this set includes perfectly matched file sizes (.013”, .017”, .024”, .032”, .042”, .056”), so you’re working accurately with the strings you actually use. No guesswork, no compromise.

What really sets these apart is the industrial-strength diamond coating. Combined with the round “string-shape” blade design, each file cuts smoothly and consistently, without bending or catching. The result is clean, precise nut slots that improve tuning stability, playability, and overall feel.

They’re also incredibly efficient — these files are designed to cut and polish at the same time, meaning you get a professional finish without needing multiple tools or extra steps.

The build quality is top-tier too. Each file features a laser-engraved size marking, so you can grab the right one instantly, and the ergonomic handles make detailed work far more comfortable. There’s even a workbench hang hole for easy storage and quick access.

They’re versatile as well, working across all common nut materials including bone, TUSQ, graphite, and even nylon — and they’re just as effective for saddle work, which is a nice bonus.

Everything comes housed in a compact aluminium case, making it easy to store, transport, or keep alongside the rest of your setup tools.

This is the kind of tool set that takes your setup work from “good enough” to properly dialled in.

It’s also exactly the sort of thing that gets a knowing nod in Musicmaker when someone’s ready to take their guitar maintenance to the next level.
