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.

Used every day. No other crowning file I've used compares. Ditto the comments recommending better labeling. Big time saver.

great file but

The main advantage over other diamond grit files is the curved ends allowing you to crown frets that are over the body. It's expensive and uncomfortable to use because it has no handle. Quality is good but I still prefer regular files

Made crowning easy, even for a beginner

I had absolutely no experience dressing frets, and was terrified at the prospect of crowing them. But, nothing ventured and nothing gained. Acquired a beater guitar to practice on and ordered this file based on the reviews. Seems very well built. I leveled the frets and then set about crowing them (using the 300 grit to play it safe.) I was amazed at how easy it was to do, as the file did all of the work. It didn't leave much behind in the way of tool marks or scratches, so polishing was easy after. Today I summoned the courage to tackle the frets on my beloved SG and it came out fantastic. My pro guitar player friend thought I'd had it professionally done, and couldn't believe it when I told him I did it myself. So long as you go easy and don't remove too much material - but this quality file got me over my fear of working on frets. Highly recommended!

Pricey but worth it

I'm really glad I have both the 300g and the 150g. It would be great if the file was labeled which side was for wide fretwire, OR if the file had 300 on one side and 150 on the other. Awesome tool.

BIG time-saver but needs a handle.

The Offset Diamond Fret File is the perfect complement to the 18" Aluminum Radius Sanding Beam for fast, precise fret dressings. It very quickly rounds the fret, keeping it centered automatically. However, you must keep filings cleaned out often (very easy to do) because too much dirt piled-up between the fret and the file will chatter a bit.

My only complaint is that after a while, it gets tiring to hold, as it could really use some kind of grip or handle. And markings could be better, like the ability to quickly tell which side is which.

Beats All the Rest

By far the best tool for fret-filing. Perfect for both full-length and partial-length filing. Renders a very nice crowning too. Gets the job done without leaving any rough marks. Expensive indeed but you won't need any other tool for all relevant tasks.

Good Tool

I've worn out 4 of these over the years. They save lots of time. I did receive one that was defective a few years back but sm immediately replaced it.

Great re-crowning File

I put off purchasing this for a long time - now I have it I have no idea how I did without it. Wished I had bought it years ago. It is a really solid and well made tool and makes light work of re-crowning.

Great file!

this is hands down the best fret file that I have used, it removes material quick and leaves pretty small scratches making polishing easier.

My only complaint: Stewmac, for the sake of other who will buy this tool, please mark which side is which! I don't how much time I have spent staring at one side, and then the other trying to figure out which one is the narrow, and which is the wide... its kinda hard to tell sometimes.

300 grit is all you need

This tool saves so much time and gives me the piece of mind to know that my fret jobs are going to be spot on. I did not want to risk messing up the frets on my guitars so I bought this file.

2 reasons i did not give it 5 starts; 1-could use some markings to identify which side is which, 2-the price WOW it is expensive. I hope it last forever.
