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 Slotting Files

This files are great for nuts, and for saddles like the ones on resonator biscuits. I'll certainly be ordering the rest of the set!

These files produce good slots but the light gage one is very flimsy and came curved. I guess from the manufacture process. Working carefully with it produced my best string seat so far. After all what don't you have to be careful with while building guitars.

The right files for the job.

There's nothing like using the perfect tool for the application. Time saver and perfect slots every time. Customers are amazed by how much better their guitars tuning stability and tone is after a nut replacement.

Great Set Of Files

By

Verified Buyer


Part of my work is, I purchase used lower price guitars that have good tone and I rework them for people wanting to learn to play. With most I have to lower the action so quality nut files are a must.
I had high expectations for all the tools that I ordered from Stewart-Macdonald and they were surpassed. The quality of each product and the service has won me over as a lifetime customer.

Glad i got em

By

Verified Buyer


After completing 2 nuts i was unhappy with i decided to suck it up and get some nut files (i got the .013, .024 and .036). WOW!!! i marked my string positions and within 5 mins was done (needed some fine tuning but very little). They may seem a bit pricy for a beginner/hobbiest, but are definitely worth the price if you plane on doing your own nut and saddle.

very good

These files make life so much easier. You can actually get by with 3 of these if you pick the right ones. I've stacked the .010 & .013's with thicker ones to get a wider slot. You can also wobble them a little to pick up a few more .001ths. If you was working on all kinds of different guitars & strings, it would pay to get the whole set.

I was impressed by the quality of these files. The string slots were precise. The files are super sharp and cut through bone with light pressure.

Great quality and durable

Great files. Anyone who's had to make .105 guage or greater with a .060 file is just spoiled when it comes to these guys. Good clean accurate cuts and they will last you just about forever!

Bass Nut Files

By

Verified Buyer


I have a P bass that was uncomfortable to play around the first few frets. I took it to the local repair shop and it took them about 2 weeks to get around to looking at it. When I got it back it was an improvement but still not good. I saw a good video on how to set up a P bass so I bought the bass nut files from Stewmac and finished the job off myself. That bass is now a pleasure to play. Something all bass players should have.
