Gauged Nut Slotting Files

About This Item

Our tempered edge-cut nut files produce round-bottom slots for nuts and saddles. Ensure your 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.

good for square strings

By
(Customer's Reviews)


These files make square nut slots, which are great if you play square strings.

For those of use who use round strings, a tangential touch to preclude the string from wandering left or right in the nut ... minimizes string damping in the nut.

A 'V'-shaped file makes for minimal string damping within the nut.

First time .

Got these so I could adjust a compensating nut and though it was my first time I made a respectable job off it. I will buy more to give me a wider range.

Gauged nut files

I have ten guitars and love to experiment, i own just about every profile of mini files, they have all been shelved since i got the right tool for the right job. Could've saved allot of heartaches, and now i love showing them off.

Essential tools, but wear down quickly

By
(Customer's Reviews)


I have made about 5 bone nuts in the past few months. It now takes me only two hours to make one, and another half hour to screw it up. These files are essential and work well. However, I find that the edges wear quickly. So use lesser tools for the rough fit, and save these for the precision finish work.

I finally broke down and purchased the guaged files for bass guitar. These things are great! Does a pro job in half the time. There's nothing like the right tool for the job! Thanks Stewart-MacDonald!

Almost too Quick for Comfort!

By
(Customer's Reviews)


These are not your ordinary files. I'm not quite sure what I was expecting when I ordered these. For many years I have become quite accustomed to using bench files and rasps. I was kind of kicking around the idea that maybe these nut files were in some way similar to Swiss cut bench files.Was I surprised!

These are like diamond coated files. They also proved to be quite evenly coated which was also a surprise and real treat because they cut better than typical bench files.

I needed to cut a new bone nut I had installed on my '77 Electra X410. These files cut VERY quickly. Almost too quick for comfort! Probably should put a warning note on them.

Of course, I was well pleased with the finish. Much smoother than I expected. I had a small piece of polishing cloth handy to clean out the string slots and they felt quite smooth as they were so I strung up the guitar and it tunes easily and holds that tune very well.

Stew-Mac has a real winner here. If you don't have any of these files you would do well to start building your set now.

Great product! Definitely the right tool for the job.

Good slot cutter

By
(Customer's Reviews)


Love these nut files but in my opinion you also need some of the abrasive cord to smooth out the slots after filing. Also in my opinion, you have to do that with any slotting files. These cut fairly quick so that's a plus.
