Hiroshima UO-CHIKYU Professional Fret Crowning Files – Set of 3 (Model 5002)

The Hiroshima UO-CHIKYU Fret Crowning Files Set (Model 5002) is the definitive gold standard for professional luthiers, guitar technicians, and serious workshop enthusiasts. Precision-crafted in Japan, this comprehensive three-piece set is specifically designed to restore the perfect rounded crown to your frets after they have been leveled. Featuring highly calibrated, concave cutting channels, these files allow you to bring your frets back to an absolute center line with flawless symmetry and unmatched efficiency.

Angkor Music Workshop Tip: Perfect Intonation Starts at the Crown

When frets are leveled, their tops become flat, which spreads out the string contact point and destroys precise intonation. Crowning shapes that flat top back into a perfect peak. The UO-CHIKYU set provides three distinct radii so you never over-file or pinch the fret wire. These files cut smooth, clean, and predictably, drastically reducing your post-filing sanding and polishing times while preserving your fret height.

E-E-A-T: Authentic Japanese Toolmaking Heritage

At Angkor Music, we stock precision luthier tools that offer exceptional reliability over thousands of hours of workshop use. Hiroshima UO-CHIKYU files are world-renowned for their ultra-hard steel composition and incredibly clean, chatter-free cutting teeth. Unlike cheap alternatives that leave deep, jagged gouges in your fret wire, these Japanese-made tools offer precise control and an exceptionally smooth surface finish.

  • Safe Edge Control: Designed to focus cutting action strictly on the shoulders of the fret, avoiding unnecessary damage to the fretboard surface.

Frequently Asked Questions

Should I tape my fretboard before using these files?
Yes. Even though these files are highly precise, we always strongly recommend masking off your fingerboard with low-tack luthier's tape or using metal fret guards to insulate the wood from accidental tool slips.

Can these files be used on stainless steel frets?
While these high-carbon steel files are exceptionally hard and can cut stainless steel, keep in mind that stainless steel fret wire is significantly harder than standard nickel-silver and will accelerate the wear of any traditional non-diamond file over time.

How do I clean metal shavings out of the file teeth?
To maintain optimal cutting efficiency, clean the concave channels regularly during use with a dedicated file card brush or a stiff brass-bristle brush to remove accumulated nickel-silver packed into the teeth.
