Offset Diamond Fret File

About This Item

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.

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. 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 tool

(Customer's Reviews)

Another great tool from stewmac, made crowning frets extremely easy for DYI like me


Quality Fret File

(Customer's Reviews)

I bought a Gibson SG standard a few years ago and recently noticed that the guy who setup the guitar left the frets he had filed down squared off and sharp. I'm a DIY guy so I read a few product reviews, watched a few how-to videos, bought the StewMac fret file, took a deep breath and started filing and sanding. I had never done any fret work prior to buying this file, but the job came out great. The frets are now smooth and polished. I'll give myself 20% of the credit and the StewMac fret file 80% for the outcome.


Quality files

(Customer's Reviews)

I purchased both files and although expensive, they are worth every penny. It took me minutes to do what normally took hours. A great purchase, highly recommended.
