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.

Works great for me!

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.

This is probably my favorite crowning file. I like it better than any of the others, and I own them all!

My first fret leveling ever attempted by me. This tool had the frets re capped in record time. It made the job very easy to undertake.

fantastic

Works awesome. I'm not very experienced with fret work, but have been a machinist for several years, so filing all sorts of stuff is second nature. Easy to use. Easily cleans out with a brass wire brush. Worth the money.

Quick, consistent results.

Such an improvement over the old toothed files! Much less polishing required after crowning. Great value for money.

Set of 3 Diamond Fret Files

By MakingMusick from Melbourne, Australia

I use these at work and at a guess they will crown several hundred entire fretboards before needing to be replaced!
It took me a while to get used to the shape, and every now again the files fall out of the handle, but the lighter weight and smaller size is less fatiguing to my arms than the other diamond files and when you do production fretwork this is very important!
I can work at high-speed with these files and have little fear of slipping off the fret, when all goes to plan crowning can be done in just a few minutes.
I have just purchased a set of all 3 for home use and expect them to last me a very long time!
Well worth the price.
Thanks StewMac :)
