Next generation fret files

A whole new idea for crowning frets. Z-File Fret Crowning Files™ won't mess up your carefully-leveled fret tops because they only touch the sides of the frets.

Won't cause string buzz. After you've leveled the frets for uniform height, your crowning file restores their rounded shape, leaving the thinnest possible line of leveled surface on top. This is when other crowning files can accidentally scrape the fret top, creating a buzzing low spot.

Z-Files don't have this problem—because they don't touch the top of the fret.

Z-File features:

Fast cutting 300-grit diamond abrasive

Unique angled cutting edges work the sides, not the tops

Our Safe Edge Z-File has an offset shape, with a smooth, non-cutting safe edge to ride on the fret, guiding your strokes as you cut just one side of the fret. Use one side of the file, then flip it to the other side.

Works on stainless frets, too!
