Gauged Nut Slotting File Set for Acoustic Guitar

Gauged Nut Slotting File Set for Acoustic Guitar

The right gauges for cutting and shaping string slots on acoustic guitars. Six files in each set.

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.

Save with the set!
StewMac tech advisors specify these sets to match your string gauge:

#0885 For Medium/Heavy Strings
0.016", 0.020", 0.028", 0.035", 0.050", and 0.056"

Just want one? Each file is also sold individually.

Match the file to the string gauge
Choose a file of the same size as the string, or no more than a few thousandths wider. By rocking the file side to side, you can widen the slot to fit a slightly wider string.

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.
