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.

The Best files you can get.

By toothinahnd from Santa Fe, New Mexico

I got this new set of files. While the teeth of these files seems a little rough at first, I believe they will break in nicely and hopefully last as long as my old set.

Great tools

Great tools; do exactly what they are designed for. Tried using rotary tools in the past for this job. Don't even try. These files do the job perfectly, with much more control and precision.

Cuts straight and fast. I don't like Double-edge Nut Files from Stewmac, but this is great tool.

Right tools for the job

By Ron Brown from Rapid City, South Dakota

After trying everything including a fingernail file, I bit the bullet and ordered a set. The right tools sure make a difference from the initial cutting of the slots to touch ups later. String buzzing is now a thing of the past, thanks!

It's impossible to file a slot for an .011 gauge string with a .012 gauge file. Thanks for making all of these sizes available

Great but be careful

By JT McGuire from Los Angeles
(Customer's Reviews) Saturday, March 16, 2013


These are nice quality files and do the job great. I'm a newbie so learn from my mistake: make sure you cut a wider slot than your string. As I was filing away and checking string height, I didn't realize the string wasn't seating all the way into the new slot. I ended up filing three of my slots way too deep. I found out days later when the strings finally worked their way all the way down. I've learned to rock the file side-to-side more than I anticipated.

Pro Results

Bottom line is if you want pro results you have to use pro tools, no way around it, as the saying goes, you get what you pay for.
