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. Simply use the same techniques you'd use for nut slotting (read more in Making a Nut, Step-by-Step). After filing to the desired depth, we suggest polishing the slot with Mitchell's Abrasive Cord to remove file marks and burrs.

Received my files within 2 weeks of ordering. They were well packed and arrived in pristine condition. I'm new to guitar building but these files are of high quality and I'm happy with them.

Mandolin nut files

First time I have ever used this type of file. I normally use a small round file, but this was much more accurate and cut a really nice slot. I'll be getting more for violin work.

I bought 8 sizes to start. I used them last night and was very pleased. I had no problem with the flex on the lighter files as I typically like to use two hands for some reason. I think I'll order the other sizes I might need today.

Great Files but................

By Rockin' Mike Burton from Canada

I used these files to slot 2 brand new nuts out of bleached bone. I found them very acurate and easy to use. They rounded the slots nicely, and with a bit of a rolling action, I was able to fine tune each slot for the player's string set. But what is with the 0.010" file? Would be nice to see a bit of extra meat in the middle of that one for some support/rigidity. The one I recieved wasn't even straight. It was in a deformed curve due to it being so flimsy. Except for the 0.010" file, I think this set is great.

Bought a pre-slotted brass nut for my Tele project. The two top slots were so shallow that the strings slipped out when bending on the lower frets. What a great job these files did (and on BRASS). Thanks Stewmac!!!!

Great products. Do their intended job with ease. The .010 needs serious reinforcement, but the others work very well.

Very perfect!!!

After several new nut installations these nut files have produced a perfect fit and precise control of slot width and depth....you gotta have these if you expect a proper string fit.

I've used these nut files for five or six years. They work well and last quite a long time. They cut relatively fast and leave a nice round bottomed hole.

This files are great for nuts, and for saddles like the ones on resonator biscuits. I'll certainly be ordering the rest of the set!
