Product Details

Our tempered edge-cut nut files produce round-bottom slots, to ensure that the 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.

Be Precise

By kilphody from NY

Your nuts are too important to do a sub-par job on! Always use the right tools for the job. Professional results don't come easy or cheap. Remember the initial cost will pay for itself many times over with quality jobs (and customer and personal satisfaction). I just used mine on a piece of black horn for a jazz box using 56-13 flatwounds. Outstanding results.

These files work very well. Slots are accurate and can be widened slightly by working the file side to side. I've been using them to slot banjo bridges and they work great.

I used these files to cut the slots in the brass saddles of the Schroeder Stoptail bridge. They cut through the brass very quickly and cleanly and made the job fun. The bridge sounds great and the additional intonation control made a good, PRS SE semi-hollow even better.

Gauged Nut Slotting File

By Stokes from CT
(Customer's Reviews) Tuesday, April 17, 2012


I ordered the 0834 .050 one. It was the first one I purchased. It worked great. As I've gotten "older" I find my neck grip is kind of like a death grip. Making me sound out of tune on the lower strings. So I wanted to go up a few string gauges. I went from .009-.046 to .010-.052 I KNOW the numbers don't match but it worked with a little bit of "rockin'". Now I'm using .010-.060. So I ordered the file to widen the lower E nut slot. Just a few passes on the Les Paul bone nut and I was done!!
The only thing that I found "wrong" was either my perception of the item-or a small item picture. It looked like the file had a small rubber "handle" or grip on it with the awesome Stew/Mac logo. But as I found out it was just painted on. Hardly a reason to form a redesign committee!! Just saw the video link-nice touches guys!!

Nut files great

By Jake's Likes from Spokane, WA

Great having properly sized files with correct profile for bottom of slot. Together with good instruction, I've vastly improved the action on my Gretsch Electromatic, my Dean Hardtail, a Taylor, and an Ibanez V series. No buzz, good intonation from proper angle and correct size for strings. Beats all of the substitutes (Needle files, etc.) hands down.
