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.

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.

Compared these to my Japanese files - smoother and less aggressive with a very nice bottom curve (almost sounds like a fine wine). Great feel and very predictable. Worth the cost, glad I got them!

Gauged Nut Slotting Files Did The Trick

By

Verified Buyer


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.

Top quality product

I run a professional shop now in our 20th year, and 40 years behind the bench: these tools are great: smooth cut, clean surface. I'll fold a piece of 800 and finish the slot and edges to debur .

Highly recommend for the pro and amateur tech or builder. The nut spacing rule is handy as well!
