Gauged Nut Slotting Files

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.


Trade Secrets!

Are you supposed to slot Tune-o-matic bridge saddles?

Customers often ask how and why they should put slots in the saddles of their new Tune-o-matic bridge. Erick Coleman provides the answers in this issue of Trade Secrets.

Good value

By

Just one teeny little niggle... The 0.010" file is thin, as you might expect. This makes it bendy and rather hard to use. You need two hands to keep it straight. So,I bought #3596 Guaged Saw to do the same job. It has a backing strip like a Tenon Saw, and can be used single handed. It's so much easier to use in practice. Other than this niggle, these files do an excellent job. If you order a set, purchase #3596 at the same time, it's only 8 bucks for a nice little saw that will save you a headache.

Great files

I bought 4 of these for Ukes - 028, 032, 035 and 042. Just file away until the file touches a 050 feeler guage placed on the fingerboard - perfect!

If you can afford these files buy them.They make your work so much faster and easier.Tip cleaners and feeler gauges for files are not accurate.These files will last forever if taken care of.

I got a set of these as a Christmas gift, from my luthier brother-in-law. As I play with dainty strings (mostly nines), I added the .010 file to the collection.

They work.

Are there better ones? Maybe...but I won't be looking for them.

They work. That's good enough for me.

invaluable

I've made countless nuts with these files. Their flat sides can be useful if using spacers to determine your slot positions. For example, I have found it useful to slot a small nut-sized piece of wood and get the spacing perfect. Then clamp this piece with your bone blank in the vise. The wooden piece acts as a template for transferring the slot positions - similar to using an old nut, but more accurate! These files are perfect for this method.

beats a pocket knife

I have two sets (one for steel strings, one for nylon strings). Use to use a gent saw and a pocket knife to make slots. These files do a wonderful job. Well worth the money.

Does the job.

Only complaint is I wish the .010 and .013 didn't wear out so fast but I guess that's to be expected since they are thin and I used them a fair amount. Works great!
