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.

Perfect tool for the job

By
(Customer's Reviews)


As a semi pro luthier for many years, i've carved and slotted dozens of nuts. I've used a variety of files to accomplish that task. Nothing comes close to the speed & accuracy that come from using these slotting files. They are the perfect tool for slotting electric or acoustic nuts.

the right tools save time and effort

By
(Customer's Reviews)


These are not cheap when you buy all the sizes.I have been improvising for years. After grinding coping saw blades thinner, notching Xacto knife blades, dressing nasty slots with dental floss and valve grinding compound, I wish I sent the money years ago. These allow precise work in almost no time and leave the slot bottoms round enough to not need to be further polished for smooth action. I have worked too long and too hard in the past to accomplish what these do in minutes.

Quality products, Files.

By
(Customer's Reviews)


While High priced, Quality IS excellent. Inspected same with a 30 pwr microscope primarily observing the bottom edge profile. These were found to BE truly ROUND; NOT V-shaped, square cut, ragged nor elliptical! Strings should FIT in slots perfectly, NO binding nor Intonation problems.
Thank you.

Pricey-Good Quality

By

Have not actually used files yet. Quality looks good and delivery was fast. Files are rather pricey,
I have found that Stew-Mac always stands behind their products. Three stars only because I have not used yet.

The best system for me

By
(Customer's Reviews)


In the past, I have used fewer files than needed, and made larger slots by slanting. The last nut that I made, I kept going a little deeper on the 5th string, but it wasn't wide enough for the string. By the time I realized that, the slot was too deep. NOW I have a file for each needed gauge and that won't happen again. They work great.

Slotting files a must have for general maintenance

By
(Customer's Reviews)


The accuracy that these files bring to nut and bridge saddles work is perfect. A must have if your going to attempt this type of work. It would be nice if they were a little less expensive or in a set discounted price. But well worth the money regadless as they do save time in setting up a new bridge or nut or just replacing saddles.
