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 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.

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.
Get a better grip on your files!
Our new Nut File Backer makes these files even easier to use. It acts like a spine, stiffening the file for a straighter, more accurate cut—no more slipping and sliding on a slick nut or saddle. We have models for narrow and wide files, giving you complete control.
