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 than a few thousandths 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.

Save 10% by purchasing the complete set
Always have the right gauge for cutting and shaping string slots on any instrument. Complete set of nineteen files includes every size we offer.

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.

No Going Back

By

Verified Buyer


I'd bought a set of these a couple years ago and thought of them as an experiment; something different from the type of slotting files I'd been using for years and years. There's no going back now ... I've just bought for inevitable replacement and expanded the set.

Excellent!

By

Verified Buyer


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.

Great file

By

Verified Buyer


I bought this file hoping to cure behind-the-nut ringing of the g string due to a bad slot on a strat. The file worked great but the string rings worse now. Maybe an added tree would do it.

Completes my nut file set.

By

Verified Buyer


I bought this to complete my nut file set. I expected a rigid back - this is very flexible as, of course, it is very thin. It should be fine for the job but will require careful handling.

Great tools!

These work great. Just take you time, and protect the bridge and the pickup covers.

You can get cheaper ones, but they are also inferior

They're GREATTTTTTT!

By

Verified Buyer


Hard, (if not impossible } to top these radiused files! Been using the 10's to 56's for umpteen years but due to Bass work increasing, decided to stop "Wallering" my slots, bite the $$ bullet, and get three of the larger sizes, ie: 65, 85, and 105. Haven't used them as yet, but am SURE that the ever-consistent Stewmac excellence will be found in these as well!
