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?

i'm nuts about your files...again!

By
(Customer's Reviews)


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

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.

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.

Nice nut slotting tools

The files seem to be good quality. They cut fairly slowly, which is good to get the slot exactly to its final depth.

Nice cuts

I ordered a set of these, which they don't seem to offer anymore. It's a good set, though I did snap one off on the very first use. It is still useable, though. With the thinner ones, you have to be very careful not to focus all your cutting force on a small area of the file. Use the whole length. That's what I've learned. Anyway, a nice set to have. They cut quickly and make nice round bottoms. Widening the Slot can be a bit tricky.

They cut a perfectly shaped string slot every time!
Much more accurate and repeatable than the small diamond files I was using before.

If you are thinking about making your own nut or modifying a "finished" nut, don't even bother using anything else. Ruined several trying a variety standard wood working tools. Ordered the gauged nut slotting files and got it perfect the first time!
