Dual-grit Diamond Fret File

2 grits in 1 file! A versatile no-chatter file for crowning frets.

Steel insert with 150 and 300-grit industrial diamond-coated concave cutting surfaces in ONE file for crowning frets. It's angled shape gives extra clearance over the guitar body at higher frets.

Our unique Dual-grit Diamond Fret File is two files in one, featuring an angled steel insert with 150 and 300-grit industrial diamond-coated concave cutting surfaces for crowning frets. Switching from one grit to the other is quick and easy; simply unsnap the file from the handle, turn the file around, and snap it in place again. The bent file shape is designed to give you extra clearance over the guitar body for shaping the higher frets. Diamond-coated cutting surfaces work on the forward and backward stroke without chattering, giving you better control for smoothly rounding the tops of the frets. The shape of the handle and 5-1/2" overall length make the tool comfortable to hold, efficient, and easy to control.

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

Our diamond fret files have concave cutting edges, one for medium and small fret wires and one for wide fretwire. Each edge is electro-coated with micro industrial diamonds. These super-tough abrasive surfaces round the frets more smoothly than standard toothed files, for cleaner filing without chatter marks. Because the diamond particles cut on the forward and backward strokes, you get better control over your work and the job goes much faster.

We offer three designs of diamond fret crowning files, each in two different grits. Diamond fret files are available in the traditional Diamond Fret File, the curved Offset Diamond Fret File, and the unique Dual-grit Diamond Fret File. If you're use to traditional fret files, you'll probably be most comfortable with the Diamond Fret File, but you may find the curved design of the Dual-grit Diamond Fret File may allow you to work more comfortably with less arm, wrist, and hand fatigue.

Dual-grit Diamond Fret File is also excellent for working on the frets in the upper registers of acoustic and set-neck electric guitars. They virtually eliminate the chances of "gouging the top".

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.

Great all-around crowning file

By
(Customer's Reviews)


Nothing beats a good cant saw file in my opinion, but if you're a novice or simply want a crowning file that gives you good, fast, consistent results with little effort, this is the guy. I would say these are the ideal crowning files for hobbyist techs, as well as environments where you are doing a high volume of crowning work and can't justify the time cost to benefit ratio of going with a cant saw file.

The biggest downsides: the shape seems to cause a bit more hand fatigue than Stew-Mac's offset diamond crowning file, and the format in which they're offered doesn't seem as value-conscious as it could/should be; They don't sell the blades/handles separately, and I wish they sold a bundle of all 3 blades and one handle at a discounted price. Aside from a situation such as managing multiple techs doing recrowns on 3 different instruments with 3 different fret sizes, I've never found myself in a situation where I needed all 3 sizes of crowning files staged and ready to go at the same time. Other than that, these are some of my favorite crowning files.

For those people complaining about the blade falling out make sure that the ball is not over the carved out side with the diamond grit.

use on older Gibson Mandola

I used this file to form the frets on a ~1920 Gibson Mandola after a light dressing. The resulting form of the top of the fret was nice (I used a magic marker before hand to stop just when the top was touched). I find however that the relatively sharp edge between the end of the round and the side of the fret now catches my fingers, so I will be filing that. Altogether good, but does not suffice alone to give a fret that feels right.
