The right gauges for cutting and shaping string slots on electric guitars. Six files in each set: choose light, medium or heavy gauge strings.
Our tempered edge-cut nut files produce round-bottom slots for nuts and saddles. Ensure your strings seat properly in the nut without buzzing!

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.
Nut slotting files work great for metal Tune-o-matic bridge saddles. After filing, polish the slot with Mitchell Abrasive Cord to remove file marks.
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.
