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.

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

Verified Buyer


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.

right tool for the job

Well before purchasing the Gauged nut files. I thought I could get away with the rather expensive set of Italian feather files. Just shows you that the right tool makes things that much easier. The slotting files are excellent. Thanks again.

Perfect for this critical task, my favourite of any I've tried, and I've tried them all! If I could only have one set of nut slotting files, these would be it. I only wish they came in a complete set too!
