StewMac Z-File Fret Crowning Files

About This Item

Next generation fret files
A whole new idea for crowning frets. Z-Files™ won't mess up your carefully-leveled fret tops because they only touch the sides of the frets.

Won't cause string buzz
After you've leveled the frets for uniform height, your crowning file restores their rounded shape, leaving the thinnest possible line of leveled surface on top. This is when other crowning files can accidentally scrape the fret top, creating a buzzing low spot.

Z-Files don't have this problem—because they don't touch the top of the fret.

    Z-File features:
  • Fast cutting 300-grit diamond abrasive
  • Unique angled cutting edges work the sides, not the tops

Three versions for any working style:

Original Z-File
Two diamond edges speed the work, shaping both sides of the fret at once. Offset angles shape the fret higher on one side while the other side works lower. Use one side of the file, then flip it to the other side.

Safe Edge Z-File
Offset shape like the Original, but with a smooth, non-cutting safe edge to ride on the fret, guiding your strokes as you cut just one side of the fret.

Centered Z-File
Two diamond edges in a centered V-shape cut both sides of the fret at the same angle. Simple to use and fast working.

Sold individually or SAVE when you buy the set of 3 files.

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.

This is fantastic!

Although I did not understand the meaning of this form at first, I was surprised when I tried it.
This "Z-file" can be processed very beautifully by using a file on both sides.
The fret of the photo is StewMac's # 152.

Awesome results!

By

Sure it's expensive, but after one L&C, I'm convinced it's one of be my best tool purchases ever. It was always a struggle for me to get good even results from a cant saw file, 3 corner file or concave toothed file. They always left long deep scratches which took forever to polish out. With my eyesight, it was a chore for me to get the sides even with a narrow flat centered top surface. My concave files (Hosco) trapped filings and gouged deeper, and too often shaved the top requiring re leveling. Then I bought the Original Z File, and this tool solved ALL of those problems. I'm able to get fast excellent results, with a nice narrow centered top. Way better results than I've ever been able to accomplish before, regardless of fret wire size, and so much faster. Polishing is way faster too, since the scratches are fine and much more uniform.

This Works!

Being fairly new to fret work, I've struggled with crowning newly leveled frets. I was surprised at the speed and accuracy I could accomplish with is file. When completed each crown looked almost exactly like pictured on the website.

Long overdue purchase

By

Verified Buyer


Yes, I too have grit my teeth every time I use another crowning fret file made by SM, as I cringed at the price of the Z-files. $100 for a file? Really? Is it worth it? Only you can judge for you.
I waited for the discount to buy, and I am very glad to have the Z-file Original.
It only took a few seconds and a few passes on a fret to see what a perfect thin intonation crown it left on a fret. Very controllable. Very efficient. Fast cutting.
Glad it did it, and now I will be working faster, more in control, and won't be gritting my teeth.

Not the best file

By

Verified Buyer


I bought this file and it barely works. I used it and still had flat frets. I had to use my old concave file to get the frets round again. This file was a waste of money to me. I am pretty upset with this z file as I expected it to work very well.

Works for me

By

Verified Buyer


When I saw this file in the catalog I recognized that it would solve the problem of taking just a little more off the fret than necessary when re-crowning with more traditional crowning files. I have used it for several guitar builds and some re-working of worn frets. I like the way it works and enjoy the control of the process. I'm using stainless steel frets on my guitars and this tool is performing fine for me.

Love this thing

I bought the centered file just to try it out see if it was really better. I use wide pyramid fret wire #0158 on just about all the guitars I work on. The centered Z file definitely help you keep the high point of the crown centered better than any other file I’ve tried. It cut pretty slow though and takes forever to get the perfect thin line you want. I have no clue how long it will last. I’ve done 9 guitars so far a few complete refrets and the rest just leveled and resurfaced and it’s still cutting great. I am gonna buy the safe edge Z file to try to help speed up the process of thinning out the crown. I have a feeling I’m going to own the complete set when it’s all said and done. Great tool guys, definitely worth the money to me.

Stunned!

By

Verified Buyer


I've had my G&L Legacy for 25 years and my 335 for 20 years. I've had the frets dressed on both guitars every 4-5 years. The results have been anywhere from disappointing to good. I wondered whether I could do a better job myself. I watched your videos and bought the slotted straightedge, the 8" sanding block (both instruments have a 12" radius) and Stikit, and the centered Z-file. The results on both instruments have far exceeded my expectations!! Both play like a dream. The notes are stunning - precision, sustain, clarity like I've never had before from either instrument.

Yeah, they're not cheap, but if you want peak performance from your guitars, they're worth it!
