Dual-edge and better clearance over the body! This well-balanced steel fret file is offset, for more comfortable fret dressing and improved clearance at higher frets.

Both full-length concave filing grooves (one for narrow/medium fretwire, and one for medium/wide wire), are uniformly coated with micro industrial-diamond particles. 8-1/2" x 1" x 5/32". Available in either 150-grit or 300-grit.

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

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 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 Offset Diamond Fret File may allow you to work more comfortably with less arm, wrist, and hand fatigue. Offset Diamond Fret Files are 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.

What grit do I need? If you're just starting out in fretting, we recommend the 300-grit files, as they don't remove too much material too soon — a mistake that many beginning fretters make. Even a professional will find the 300-grit file allows them to quickly get the fret properly crowned after only a few strokes.

Use the 150-grit when you need to mill-off lots of material in a hurry.

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.

Offset Diamond File

By Allen McFarlen from Australia
(Customer's Reviews) Wednesday, November 10, 2010

This file works great, but it's a little more aggressive than what I had hoped. I'll be adding the finer one to the tool kit, and will most likely be the one I reach for most often.

I used to do fret crowning old school with the three corner file. It was so time consuming. When I got the diamond fret file it more then cut my time in half and did a 100% better job in accuracy.

They work great!!! They cut very smooth making finishing the fret easy. I got 150 & 300 grit. I use the 150 to take down the high spot & finish off with the 300 grit. Then polish with 600 paper.

We use these in the shop...

I used to use the regular 3-in-1 crowning file for my fret jobs. Guys at Teye Guitars turned me on to this one. Cuts down on the time need to re-crown and polish the frets. Doesn't leave chatter marks that you have to sand out later. Worth the money for sure, great value.

best crowning file I've ever used

By Brant from Boston, MA

Very accurate and very fast. I use the 150 grit with the metal fingerboard protectors and then polish with finer grit sandpaper and steel wool.

The only reason it gets 4 stars instead of 5 is because the first one I got was defective. The surface started to flake off by the time I was working on my 3rd or so guitar. StewMac was great about replacing it at no cost.

Nice Tool!

Excellent speed & accuracy. Comfortable to use, even when working over the top of a guitar.

Mine tended to scratch the fingerboard, so I filed the edges down a bit to get better clearance.

If I ever wear this one out, I will definitely buy another.
