Gauged Nut Slotting Files

It's impossible to file a slot for an .011 gauge string with a .012 gauge file. Thanks for making all of these sizes available

Has helped us in the workshop with a lot of fine tuning jobs.Thanks Stewart Mac

These are nice quality files and do the job great. I'm a newbie so learn from my mistake: make sure you cut a wider slot than your string. As I was filing away and checking string height, I didn't realize the string wasn't seating all the way into the new slot. I ended up filing three of my slots way too deep. I found out days later when the strings finally worked their way all the way down. I've learned to rock the file side-to-side more than I anticipated.

Bottom line is if you want pro results you have to use pro tools, no way around it, as the saying goes, you get what you pay for.

I've tried many different tools and methods for nut slotting over the last thirteen years and have yet to find a more practical and effective means of getting the job done. I have yet to wear one out, even with a few MOP nuts in the mix. You might want to add a "backbone" to the .010" file however. I cut a couple strips of Ipe wood (very stiff) 1/16" X 3/16" X 5-7/8" and ca glued them down the center of each side of the file while holding everything perfectly flat. The wood gives it a nice grip while keeping it straight and rigid. A little bevel on the business end and it still slips into the protective sleeve it came in. I use a little white paraffin to lube the files when they get "bindy" in bone or MOP. Great little (simple) tools.

I recently purchased these nut slotting files and found them to be the perfect solution to a deceptively simple task. Especially for the larger A and E strings

I've only used them on a pre-slotted, plastic nut so far, and it took forever just to deepen the existing cuts a little bit. Like sawing tree branches with a butter knife.

works exactly as advertised. Watch out - it's easy to cut too much! The narrower they are, the faster they cut.

Excellent file for making exact sized slots in nuts.

For the job, these files work perfectly. The only drawback is that the paint on the handle end gets smudged in minutes of use, so in order not to lose the gauge markings I had to wrap all my files' ends in clear scotch tape for protection. An extra coat of clear lacquer on the handles would be welcome.
