StewMac Gauged Nut Slotting Files, Complete Set of 19 (0928)

Ensure your strings seat properly in the nut without buzzing!

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

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.

Save 10% by purchasing this complete set. Always have the right gauge for cutting and shaping string slots on any instrument, from ukulele, banjo and mandolin to bass guitar. This complete set of nineteen files includes every size we offer, in the following widths:

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 an abrasive cord to remove file marks and burrs.
