StewMac Guitar Nut File Backer for Narrow Files, Nut Slotting Tool | Stabilizing Backer for Accurate Slotting, Filing and Alignment, Keeps Narrow Nut Files Straight for Clean Precise Slots
Nut File Backer
Get a grip on thin files!
Stop those skinny files from jumping, wandering, and bending.
Comfortable grip for easy, accurate slotting
Gauged Nut Slotting Files great, but the thin ones can be tough to hold. It's hard to start a slot without the file chattering or drifting off your line—one small mistake can ruin a new nut. The handy Nut File Backer acts like a spine, stiffening the file for a straighter, more accurate cut. And it's much easier to hold on to: no more slipping and sliding on a slick nut or saddle.
Easy alignment and no more bent files
It's important to hold your files perfectly horizontal when filing new slots, and this backer makes it easy to tell when your alignment is just right. The file is supported along its entire length—you'll never need to worry about bending your files.
How it works
Simply slide your file into the backer, tighten the 4 hex screws, then file away! Switching out files is a breeze. No special tools needed, any 1/16" hex key will work. Just loosen the screws, swap the files, tighten, and you're ready to go.
