Product Details

This wooden-handled file features three interchangeable 1-7/8" hollow burrs for recrowning a wide range of fret widths, from basses and guitars to mandolins.

The 4-1/2" long steel shank is angled for efficiency and clearance over the guitar body. Useful for a wide range of fret widths, from basses and guitars to mandolins.

#0685 Includes 1 wooden-handled file and 3 burrs in these sizes:
- Narrow, 3/32"
- Medium, 1/8"
- Wide, 3/16"

Replacement burrs sold separately.

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 and Fret Cutters. 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.

Gurian fret file

By DoC Kildare from Derbyshire, UK
(Customer's Reviews) Wednesday, January 16, 2013


Nice, ergonomic shape, easy to use. Does what it's supposed to do. My only criticism would be the ease with which the larger blades come out of the handle, but I sorted that by using a washer with the bolt to create a larger area to hold the blade in.

A great tool for the job.

I had dressed frets with a number of different methods before, but this was my first full fret replacement job. I'm a hobbiest, so I didn't want to spend too much. These files worked great for my situation. Thanks Stew-mac.

great design

This file is so easy to use and the angled handle is great for getting into tight spots around the body. The wooden grip is comfortable to work with.

3-in-1 file is great!

I've used numerous files over my 25+years of guitar repair. I finally broke down and bought a new one of these as the old one I had finally wore out. It's probably my favorite file of them all, except for maybe the offset diamond file. I use these to "rough-in" the fret crowns, go over it with the diamond files, and use the sanding stick with 600 or 800 grit belt before using the micro mesh finishing pads for a high shine. I highly recommend this file as it covers all fret sizes and is easy to use.

Great choice for getting started

By Patrick Taylor from Toronto, Canada

If you're just getting started with building or doing your own repairs, the Three-in-one Fret File is a good choice for getting tooled up. The concave burr surface makes recrowning much easier than doing it by a standard fret file. The handle puts the file a perfect angle for avoiding fatigue. Being prone to carpal tunnel syndrome, this is a major concern for me when choosing tools. While you might want to upgrade to diamond fret files later, if you get more serious, this tool gets you started without being a major cash outlay. I know I will get plenty of use out this. Well worth the price!

Fast and accurate

Been in the luthier business for 4 decades. Using this tool has cut fretwork down so much it's no longer a major chore to do. The file lines up well. Dresses and crowns with no chatter or deep markes in the frets. Polishing after is almost a thing of the past. Paid for itself with the first use. Great tool to have.

Versitle and good value

By Ray W. from Minneapolis
(Customer's Reviews) Friday, August 24, 2012


I've used the three-in-one file on 8 guitar builds for crowning frets after leveling. It does an excellent job, although it is slower than a diamond file - but that may be a good thing because it slows you down on softer frets. You do need to be careful not to start cutting into the fret board next to the frets

Occassional Use

By Patrick Patten, Patten Guitars from Fredericton, NB Canada
(Customer's Reviews) Wednesday, August 08, 2012


If you only do fret work once in a while then this might be the tool for you, especially when working up near the body. Otherwise the diamond fret files have taken over !! But it is still good value for the money for the occassional user.
