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 than a few thousandths 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.

Save 10% by purchasing the complete set
Always have the right gauge for cutting and shaping string slots on any instrument. Complete set of nineteen files includes every size we offer.

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.

Nut Slottin  Files are needed if you setup your own guitars.

By

After restringing, trust rod adjustment, and bridge height adjustment the next thing is the nut slot adjustments. To do this right you need all the different widths for the string you are using. I have used the Gauged Nut Slotting Files on all my guitars. This is how I get the best action for me on everything I play. You must be careful to use the right width for each string and not to go too deep. The angle is important, to follow the line from the nut to the tuner post. Great tools, great buys.

I bought this file for my guitar shop. I thought it would be stiffer than it was. Works well but is pretty flimsy.

right tools for the job

I started buying these files when I needed to make a new nut for a mandolin I had bought. They were the perfect tool for the job. You can make string slots that are the right size with an even radius every time with no guesswork.I like them so well that I bought more to fill in the blanks for doing guitar work. Nothing like having the right tool to do the job right the first time. The appearance of finished guitar nuts is worth the cost of these files when you compare them to the off the shelf variety with slots that look like feed troughs by comparison. I even use them for fiddles now. I don't know why anyone would try to get by without them.

No substitute!

As a hobbyist, I've tried everything from welding tip cleaners to razor saws basically trying to save a few bucks. Don't waste your time or money on anything else. These are the ONLY tools for the job.

Guaged nut slotting files

By

Verified Buyer


I love these files. They make accurate slot sizing a breeze. I work on violins, violas, and cellos, and no two strings are the same size. After measuring the string diameter, I can make custom-sized slots by angling the file from side to side as I cut. I've also successfully used two files together to make a more accurate slot. I have 9 files now, will probably buy more.

The only down-side is with the very thin files. They are difficult to use on very hard woods like ebony, they tend to bind and fish-tale. But with a little practice, I've been able to use them successfully.
