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!

Great files.

I had delayed a long time contemplating whether or not it was worth the money to get nut slotting files. I have a thin needle file that I've used to make a few nuts...and I got pretty decent results after a LOT of filing. These files are fantastic. I personally purchased 6 different gauges ranging from .01" to .050" but for those looking to save money, you can get by with 3 sizes. I've used these to make a few dozen nuts and to touch up and re-cut existing nuts and they still file perfectly. I would recommend these over the double edge files because you get two sides on each of these files so when one begins to get dull, the other side is fresh. Great files.

My favorites so far

I like these best of all the nut slotting files I’ve tried. The bottoms of the slots come out truly rounded. I have a set of similar slotting files, purchased from StewMac about 20 years ago, and the current files are an improvement - they are definitely rounder - closer to a half circle than the old ones.
The one difficulty I’ve had with these is that when the very thin files get down to a certain depth, the file starts to get hung up in the nut material – the same way a saw might get hung up in wood when you get too deep...but that’s not a problem with the file, per se. I may fix this by cutting the top of the nut lower before I deepen the slots.

I love my .010 gauge file! It's the best way to start my nut slotting especially for the treble strings.
