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.

Great tool.

Purchased to do one of my Guitars, wasn't thinking I have 6 with all different strings and sizes should have ordered all of them. The Luthier I use must have had a new person answering his phone. Needless to say he lost some work.

Fine quality files; worked well to lower the action at the nut. They do what they're intended to do.

Like many, I made due with various lesser files and was never quite satisfied with the outcome. What a waste of time and effort. These nut files work perfectly the first time, are easy to control, and cut the slot the way it is meant to be done. Actually cost less than the drawer full of assorted files I've been using.

specific, useful

I bought several of these files for their intended purpose: (re)slotting the nut on several guitars and ukuleles. The width measurements are precise, and the file edges uniform, which makes them far better for this than any of my bench files. If this is a task you plan to perform more than once or twice, they are worth buying.

Gauged Nut Slotting Files Did The Trick

By
(Customer's Reviews)


I purchase a new Telecaster that came with 9's strung on it. I prefer 12's, but the slots were too narrow for the four low strings. I order four files that most closely matched by favorite set of strings. A couple swipes with the files for their respective slots and the strings seated perfectly. The quality of the files made for the quick DIY adjustments.
