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.

Double edge nut file

By

Verified Buyer


When my order arrived I had two instruments on the bench ready for nuts and saddles. This file made this fitting so much easier that I wish I had bought one years ago. I had hesitated because it seemed a little pricey but having used it, I believe it is worth every penny. You really do get what you pay for and once again StewMac did not let me down.

I used a set like this several years when I worked for someone else. I bought the same set for my own shop. It's pretty much a must have item (among many).
The set from my previous job was tough, durable easy to use and helped me make some money. I expect this set will be the same. I put them to work right away.

Perfect cut every time

The double size saved me a couple bucks over the singles, and had sizes not available in singles.
Wish the different size sides were labeled.

'Must-Have' tools for nut making or set-ups

I love these nut files! They're rigid and the perfect 'V' shape which make it very easy to cut an accurate string slot. No more tuning issues caused by binding in the nuts on any of my guitars!

Great files!

I've been fighting with my set of gauged nut files. Even with shallow slots in a nut close to final shape, the files still bind.

Finally, I gave in and bought a set of these. WOW! Since they're angled, and cut on the sides, not the edge, there's no binding at all. I was concerned about the V-shaped slots these files create, but if they're as shallow as they should be, it's not an issue.

My only wish is for a couple more interim gauges, especially a .016, and a .056.

I don't have any issue with the poor labeling. Sure, etched markings would be nice, but as it stands, if I hold the file so that I can read the label printed on the handle, the lower file is always the smaller one. Just chance? I don't know, but it works for me.

Very good...but with a couple of faults

By

Verified Buyer


I bought the full set of these files several years ago. Let's face it, they're very expensive for what they are but hey, they do the job.

Issues: I agree with other reviewers that they should be etched with which size is on what side. It's almost impossible to tell with the naked eye. I wrote it on with a CD marker pen and it's stayed on there.

The other problem I have is when cutting an acoustic bone nut. I like to start with the blank way over size and cut the slots pretty deep. This way you can adjust the string spacing. The problem is that the cutting surface of the files only extends a small way up the side of the file so when you get to any depth you have to start tilting the file to widen the cut or you just get chattering and very little cut.

But all in all, a good (if not essential) product.

As with all of my other Stew/Mac purchases, this one is top notch and a must have for any serious repairman, technician, or Luthier.

We use this and many other Stew/Mac tools during manufacturing and setups on all of our Sterling by Music Man and B.C. Rich guitars and basses.
