Double-edge Nut Files

About This Item

The most durable and efficient nut-slotting files available. Specially designed for nut slotting, each file cuts two different width slots.

Each 9/16" x 7-5/8" (14.29mm x 193.67mm) steel file cuts on the edges only, and tapers from the center to a different thickness on each cutting edge. The set of six files does the work of twelve!

Rubber-coated handles give firm, comfortable control for the job. The complete set includes edge widths for filing round-bottom nut slots on most stringed instruments, including basses. Each file's cutting edge is approximately 3-7/8" (98.43mm) long.

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.

The most popular Double-edge Nut Files are included in the Essential Nut Making Tool Kit, which has all the basic tools you'll need for shaping, string-spacing, slotting and fitting string nuts like a pro.

Tip: Customize your files
We recommend that you mark on each side of your files so while working you can quickly tell the different gauge of cut.

Here's how: make a cut on a scrap piece of bone or wood with both sides of the nut file, then measure the width of each cut with feeler gauges to determine which side is which. Guitar strings of known gauges will also work as measuring tools in a pinch.

Once you have determined the proper edge, mark the file accordingly with a permanent marker.

Nuts no longer drive me nuts!

By

I do luthier work for a large school district. This set of files make short work of nut slotting for the violins, cellos, and basses I maintain. The twelve different sized edges are sharp and precise. I really like them.

Good files, but for the price they can tell us which side is which.

By

These do the job nicely, but they're expensive, and for the money they can tell us which side is which. The manufacturer certainly knows. I wouldn't be surprised if they print the handles on a side that's consistent with the large/small orientation. It's just a matter of the manufacturer or Stewmac telling us the scheme. Alternatively, they could make the files in combo gauges that are easy to eyeball, like 10/26, 13/36, 18/46, 24/56, etc.

Great for Cello/bass repair

We use the double edge nut files daily. They have a nice, sharp cutting surface and enable us to get nice straight grooves on the nuts and saddle of our cellos and basses.

J'ai maintenant toutes les dimensions de limes dont j'ai besoin. Bonne résistance à l'usure même sur des sillets de bronze.

Poor Tolerances

By
(Customer's Reviews)


Out of the 4 nut files I received, the edge grind on 2 were so poor that only about 20% of the file length was usable. Both ends were filed to a near-knife point, rather than the .020" or larger specification. The width of the file cut is within about a 200% tolerance (.020" could be anything from .010" to .035" depending on where on the edge you're cutting).

Dull quickly....

By
(Customer's Reviews)


To be fair, I have been very satisfied with all the products I have purchased from Stew Mac. These files however are the one exception. Given their cost, they dull way too quickly. They are fine for softer plastic and graphite nuts but for harder bone, brass, etc., you are lucky if you get a half dozen good jobs out of them. 'Recommend for the weekend luthier but not for the pro. Stew Mac, you can do better.

No substitute for these

I have tried all the poor-man's work-arounds; welding tip cleaners, needle files, you name it. Finally sprung for a small assortment of these, and holy cow, I can't believe how much faster, easier and more accurately you can slot a nut with them. Nice quality, cuts a metal saddle with ease too.

Good quality

I work on both basses and guitars and find the use for all of the files in the set from the smallest to the biggest gauge. They cut well and leave well shaped slots - no string binding, no side-to-side wandering. Couldn't be happier!
