Details

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.

Work great

By Mike T. from North Carolina, USA
(Customer's Reviews) Thursday, September 15, 2011


These files work great. I don't mean to beat a dead horse, but the labeling is the reason for 4 stars. Not hard to figure it out, just a nuisance to have to label a new tool.

Happy..!

Bought them 'cause we use the same files at our luthier school. Files work like a charm, very happy with it.

double edge nut files...

By Rob the luthier from Scotland

Great files, the full kit covers all types of instrument, my only gripe is like others have stated the sizes are only printed in ink on the rubber sleeves which wear off quickly, good files though...

Great files.

I use these nearly every day. I've cut many nuts and even slotted the saddles on 2 tune o matic bridges. As long as you use with care, there's no reason these shouldn't last for a long time.
Only complaint is that the sizes don't go lower than 0.010" which is the only reason I gave it 4 stars rather than 5.

mr fix it .

Double Edge Nut Files

By J.C. Moranville from Colorado
(Customer's Reviews) Thursday, July 21, 2011


I talked to Casey at Stewmac and asked
which end was which. The labeling does
not show the width of cut.

Take a piece of hard wood and make about 3 or 4 passes on what you may think is the 'skinny' side, flip the file and if it binds that's the 'fat'
side. Take a marker and label, but you
guys knew that. Right?

Excellent durable nut files!

Very satisfactory tools

By Lucien from France

Good tools but the size directly on the file is missing.

Use them everyday

By P Smith from Cary, NC
(Customer's Reviews) Saturday, June 25, 2011


Wouldn't be without them. Only issue is it would be nice to have the size labels more clearly delineate which side of the file is what size especially in the smaller sizes. Sometimes it's hard to tell.

Easier than my set of 10

By Julyan Wallis, Guitar Doctor / J Gu from Cornwall, UK

HARD wearing, have gone through a lot of sets of the separate nut file sets from other suppliers which clog and are hard to clean. Simple to work out which side is which by filing on scrap wood, it's visible to see the thicker edge.
