This well-balanced dual-edge steel fret file has an offset shape, for more comfortable fret dressing and improved clearance over the guitar body 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.
