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.

Tools that perform better than expected.

I recently purchased these nut slotting files and found them to be the perfect solution to a deceptively simple task. Especially for the larger A and E strings

Cuts SLOW!

By
(Customer's Reviews)


I've only used them on a pre-slotted, plastic nut so far, and it took forever just to deepen the existing cuts a little bit. Like sawing tree branches with a butter knife.

works exactly as advertised. Watch out - it's easy to cut too much! The narrower they are, the faster they cut.

Excellent file for making exact sized slots in nuts.

Working perfectly, should be better protected

By

For the job, these files work perfectly. The only drawback is that the paint on the handle end gets smudged in minutes of use, so in order not to lose the gauge markings I had to wrap all my files' ends in clear scotch tape for protection. An extra coat of clear lacquer on the handles would be welcome.

Very easy to use and saved me a ton of time. Last nut I cut with swiss files. Turned out good, but since I intend to build several more instruments, seemed like an easy purchase to justify. So much easier to fine tune the depths.

There is no substitute for having a quality tool to work with. Having tried using a cheap gas torch tip cleaner on previous projects, the StewMac Nut files are the only way to go. The control, ease and speed of task time is appreciated.

Gauged Nut File- Improvement

By
(Customer's Reviews)


I just received these Nut Files and I am sure they will do a great job, but I feel the thinner ones .010" to .20" need to have a stiffener added on either the sides or top to keep the file straight. The .010" is particularly 'bendy'.

I've used these files on bass guitars up to mandolins. They are easy to use, and have the perfect cross section for string fit. Gives a professional finish to the job.
