Gauged Nut Slotting Files

Our tempered edge-cut nut files produce round-bottom slots for nuts and saddles. Ensure your strings seat properly in the nut without buzzing!

Each chrome-alloy steel file has twin 4" cutting edges. Among our most popular tools, these professional files help you get the job done quickly and correctly.

What files do I need?
Choose nut slotting files that are the same size or no more that a few thousands larger than your individual string gauges. A smaller file can also be rocked side-to-side to widen a slot to the desired size. For example, you can cut a .043" slot with a .042" file by moving it around a bit.

Tip: Slotting Tune-o-matic style saddles
Nut slotting files work great for metal saddles. Choose your file size as you would when slotting a nut: use the same gauge as the string, or a few thousandths larger. After filing to the desired depth, we suggest polishing the slot with Mitchell's Abrasive Cord to remove file marks and burrs.


Trade Secrets!

Are you supposed to slot Tune-o-matic bridge saddles?

Customers often ask how and why they should put slots in the saddles of their new Tune-o-matic bridge. Erick Coleman provides the answers in this issue of Trade Secrets.

These cut perfect string slots. Nice profile, good grit. They cut fast, so be careful and take your time. They do a great job!

Finally broke down and bought a proper set of nut slotting files. I'm impressed by how fast and straight they can slot bone nuts. Even you, tiny little 0.010" file! You're tougher than you look.

These gauged nut files are great.

By
(Customer's Reviews)


I just bought an assortment of these, and did the set up on an 1890's S.S. Stewart banjo as soon as I got them. I've always used Grobet nut files and I love them, but they are getting harder to find, getting more expensive with current exchange rates, and there are a lot more sizes of these gauged nut slotting files than Grobet offers.


It was hard to make the plunge and cross over from what I was used to, but so far I am very happy with these. I can not yet say how well they hold up in the long term, but as far as using them I am very happy and it was great having more precise sizes to choose from (important when using Aquila nylgut strings). I will add that (as with any nut file) a little wax on the sides makes using them very smooth.

Maybe these files are slightly overpriced, but what else will do their work?

Bone nut adjustments

These files made a great difference to adjusting the bone nut and saddle on a J-185 guitar - far better than trying to guess the right part of a swiss file to use - been there!

Stwe-Mac gauged nut files

By
(Customer's Reviews)


After reading comments about other vendor's files not cutting cleanly and loading up with nut material I decided to go with the slightly more expensive ones from Stew-Mac.

I've now cut several nuts of different material and can say definitively that these files are everything you could want - in terms of smooth, clean, and secure cutting.

They're easy to use, easy to control, and produce an excellent result.

Improved Stew-Mac Nut Files

By
(Customer's Reviews)


I had the opportunity to demo Stew-Mac's new and improved nut files and I was so very impressed that I did not hesitate to purchase replacements for some of my older files.



The new nut files have a much more uniform and aggressive cutting pattern when viewed under magnification. As such the cut is more predictable, uniform, and in my opinion easier as well.



I also have a full suite of Grobet files which prior to trying Stew-Mac's new and improved nut files had been my favorite. Not anymore though - once again Stew-Mac comes through with an excellent tool at a very competitive price.



Thanks Stew-Mac!

Right Tool

Gotta love having the right tool for the job. I used to use needle files for nut slots but these are faster and leave the slot smoother for less sticking and smoother tuning.

Nut Files

I have just gone through the process of building my first banjo. The second one is already started! although I did not have to buy many "special" tools, I'm glad I spent the money on the nut files. The strings are set perfectly with no rattle or buzz. The banjo has great tone.
