StewMac Z-File Fret Crowning Files

Next generation fret files
A whole new idea for crowning frets. Z-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

Three versions for any working style:

Original Z-File
Two diamond edges speed the work, shaping both sides of the fret at once. Offset angles shape the fret higher on one side while the other side works lower. Use one side of the file, then flip it to the other side.

Safe Edge Z-File
Offset shape like the Original, but with a smooth, non-cutting safe edge to ride on the fret, guiding your strokes as you cut just one side of the fret.

Centered Z-File
Two diamond edges in a centered V-shape cut both sides of the fret at the same angle. Simple to use and fast working.

Sold individually or SAVE when you buy the set of 3 files.

Want a new twist on this file? Try the Compact Z-File. It has the same shape but with no handle—making it easy to work anywhere on the neck. You’ll never run into the top or cutaways again.

Works on stainless frets, too!
All of our tools are suitable for use on stainless-steel fretwire*. Modern stainless-steel fretwire is known to be harder than the traditional nickel-silver blends, but our own shop experience indicates the wire does not cause premature wear of files or sandpapers.
*Excludes our original Fret Tang Nippers. We recommend our Deluxe Fret Tang Nippers for stainless-steel fretwire.
