Gauged Nut Slotting Files

About This Item

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.

The right files for the job.

There's nothing like using the perfect tool for the application. Time saver and perfect slots every time. Customers are amazed by how much better their guitars tuning stability and tone is after a nut replacement.

Great Set Of Files

By
(Customer's Reviews)


Part of my work is, I purchase used lower price guitars that have good tone and I rework them for people wanting to learn to play. With most I have to lower the action so quality nut files are a must.
I had high expectations for all the tools that I ordered from Stewart-Macdonald and they were surpassed. The quality of each product and the service has won me over as a lifetime customer.

Glad i got em

After completing 2 nuts i was unhappy with i decided to suck it up and get some nut files (i got the .013, .024 and .036). WOW!!! i marked my string positions and within 5 mins was done (needed some fine tuning but very little). They may seem a bit pricy for a beginner/hobbiest, but are definitely worth the price if you plane on doing your own nut and saddle.

very good

These files make life so much easier. You can actually get by with 3 of these if you pick the right ones. I've stacked the .010 & .013's with thicker ones to get a wider slot. You can also wobble them a little to pick up a few more .001ths. If you was working on all kinds of different guitars & strings, it would pay to get the whole set.

I was impressed by the quality of these files. The string slots were precise. The files are super sharp and cut through bone with light pressure.

i'm nuts about your files...again!

for a newbie, i thought i'd never actually have to order another set of nut files, but since the first ones from stew mac worked so well, i thought i'd go with them again....i didn't wear out the first ones, i lost them. only suggestion would be to have a hole in them in order to hang them on a nail or such. I haven't tried to drill them, but bet their a bugger. nice files.

Good files. Like any files they have their own touch. I find these files do the job great once you get a feel for them. Expensive, but worth it for me.

The .010 file

(Customer's Reviews)


3 stars due to the total lack of rigidity. Can't see this being very useful for nuts without adding some back bone (as others have mentioned) to keep it rigid and straight.

Thin files aren't strong enough.

By
(Customer's Reviews)


I have a set of the other Double Edged nut files, which are better in my opinion. But as they don't have .010 or .046 gauges I ordered these gauged files. No complaints with the .046. The .010 had a curve in it. Stewmac were quick to send me a replacement and well packaged, but it to was warped. I put it down to the travelling conditions, but I am sure they wouldn't be very sturdy upon use given this. These files aren't thick in the middle and then tapered to the edge of the file, like the double edged files, which makes the thinner files weak.
