Four-Size Diamond Fret File with Two Fingerboard Protectors

Refine fret crowns with a diamond-grit file offering four groove widths. The included fingerboard protectors help cover the surrounding surface during filing and polishing.

Shape fret crowns with a matching groove

✅ Match the file to different fret widths with 1.5, 2, 3 and 4 mm grooves.

✅ Shape a rounded crown using the diamond-grit working surface.

✅ Cover the adjacent fingerboard with the two included protectors.

✅ Control the file through its wooden handle.

Check groove fit against the fret before working. The narrower grooves suit smaller frets, while the 3 and 4 mm grooves are intended for wider frets.

The package includes one fret file and two fingerboard protectors. Instruments and other workshop items in the images are not included.

The file measures approximately 227 × 20 × 20 mm overall.
