SM6420 StewMac Original compact Z-File fret crowning file, 150-grit

Now our revolutionary Z-Files? are ergonomically re-designed for better control anywhere on the fretboard?even over the body! Diamond-coated Z-Files completely changed fret crowning forever: they've made it faster and easier for anyone, pro or beginner, to get perfectly rounded frets in no time at all. Our crew took the design one step further for even better results.

We've replaced the handle with a comfortable rubber grip that goes around the entire file. Now pressure is applied from the top, rather than the end, giving you greater control and pinpoint accuracy exactly where you need it. You can feel how the file is cutting better than ever before. The new design not only fits your hand better, it also makes the entire fretboard accessible. No more worries about the file scratching the top or the handle bumping into the cutaways, it's the perfect size to stay on the fretboard. And it's easier to reach all sides of the fret, no need to flip the instrument halfway through the job.

After you've leveled the frets for uniform height, the next step is using a crowning file to restore their rounded shape, leaving the thinnest possible line of leveled surface on top. Traditional files can be hard to control, and it's easy to scrape the fret top, creating a buzzing low spot. Z-Files won't mess up your carefully-leveled fret tops?the abrasives only touch the sides of the frets. The shape keeps you on the fret and the diamond coating works faster and smoother than traditional toothed files.

All of our tools are suitable for use on stainless-steel fretwire*. Modern stainless-steel fretwire is known to be harder than the traditional nickel-silver blends, but our own shop experience indicates the wire does not cause premature wear of files or sandpapers.
