Diamond Fret Crowning File - 3mm

The Northwest Guitars Diamond Files are the ultimate tool for quickly restoring a perfect crown to freshly leveled frets.

Long-Lasting Diamond Coating

Electro-coated with industrial-grade micro diamonds, these files are exceptionally durable, providing smooth, precise fret rounding that stays sharp far longer than traditional toothed files.

Superior Control and Efficiency

Unlike traditional files, the diamond coating cuts on both the push and pull strokes, giving you better control, faster results, and a smoother finish without chatter or file marks.

Double-Edge Design for Versatility

• 150-grit quickly removes material and restores the crown.

• 300-grit leaves a surface ready to polish to a mirror-like shine.

• Works on stainless-steel frets as well as nickel-silver
