StewMac Double-edge Diamond Fret Files

About This Item

Diamond fret files are the best way to crown your frets!
Unlike traditional fret files, diamond files cut in both directions, they don't chatter, and the fret is smoother after crowning. These files are being used by repair shops and major manufacturers all around the world.

Long-lasting diamond coating
Each file edge is electro-coated with micro industrial diamonds. These super-tough abrasive surfaces round the frets more smoothly and stay sharp longer than standard toothed files.

Better control, faster work
Diamond particles cut on both the push and pull stroke (traditional files only cut one way). This gives better control over your work, and the job goes much faster.

Double-edge covers more instruments
Each file has hollow-ground cutters in two sizes for crowning a variety of fretwire. Narrow/Medium files are for mandolin, banjo and guitar fretwire. Wide and Jumbo are for guitars and basses.

  • Made of tool steel
  • 150 or 300-grit diamond coated edge
  • Comfortable rubber-coated handle
  • File cutting edge: 4" (101.60mm)
  • Overall file size: 7-3/8" x 5/8" (187.33mm x 15.88mm)

Works on stainless frets, too!
All of our tools are suitable for use on stainless-steel fretwire, with the exception of our Fret Tang Nippers. 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.

Cuts fast even stainless

A must have for any serious workshop

It slips too well.

By

Verified Buyer


Things that were produced in the past were very good.
However, this does not match the concave surface and the fret is always too flat when checked after fret crowning.
And because the concave surface does not match, I can work so hard that I can not get it to work properly so that I slip down and slip down to scratch the fingerboard.

This needs some improvement.

Good File That Leaves A Nice Finish

By

Verified Buyer


This is my first diamond crowning file and I am very pleased with it. I generally start a job with a steel crowning file and then remove the last bits of the lands this one. The grit leaves a nice satin finish that is ready for polishing. The only complaint I have about this file is the length and the fact that the grove narrows at the tip causing the file to flip off of the fret if you pull it back too far. Another 3/4" longer and this file would be much better. I have not experienced the issues with too much metal being removed from the fret tops some of the other reviewers have mentioned.

to shallow

After leveling all my frets with a radius block and sandpaper I used this file to crown the frets,
to my surprise this file did not shaped a nice crown on the fret, it actually removed some more material from the top of the fret. even though I was using a fingerboard guard that raised the file even more from the top fret, this thing does not work as it should I'll stick with my 3 corner file.

Response from StewMac


We are sorry to hear you weren't happy with how this file worked. A lot of variables can come into play when using this type of a file including the motion of the file, the dimensions of the fret and how much material was removed when leveling. We would be happy to try and troubleshoot this with you over the phone or via email. If that doesn't work for you or if you would prefer a refund, please let us know and we would be happy to oblige.

Not quite as good as those that they replaced.

By

Verified Buyer


This file does a fine job. However, the model that it replaced had about a 2" longer cutting surface. As such, it lasted longer and was easier to control. Add in that these new ones are more expensive, and I'll admit…I'm a little disappointed.
