Hiroshima UO-CHIKYU Gauged Guitar Nut Files – 8-Piece Master Set (.010" - .056")

The Hiroshima UO-CHIKYU Gauged Guitar Nut Files Set (Model 5001) is widely recognized as the ultimate precision slotting system by master luthiers and world-class guitar factories. Handcrafted in Hiroshima, Japan, this premium 8-piece set features exact gauges ranging from .010" to .056". These dimensions perfectly match the most popular electric and acoustic guitar string sets on the market, allowing you to cut flawlessly matched slots into bone, horn, wood, and hard composite materials with surgical accuracy.

Angkor Music Technical Insight: Round-Bottom Engineering vs. Fret Buzz

Cheap, flat-edged, or makeshift V-shaped files create unstable nut slots that pinch the strings, ruining tuning stability and causing relentless open-string fret buzz. UO-CHIKYU nut files are engineered with a true Round Bottom profile. This matches the natural radius of your guitar strings perfectly, ensuring maximum acoustic transfer to the neck, silky smooth tuning stability, and complete elimination of unwanted harmonic vibration at the headstock.

E-E-A-T: The Global Industry Standard Since 1937

At Angkor Music, we source authentic tools steeped in manufacturing excellence. Founded in 1937, Hiroshima Yasuri established a legendary reputation for general metal file production before answering the call of major Japanese, American, and European custom-shop luthiers in 1983 to build specialized instrument tools. Today, their double-sided, identical-cut files remain the undisputed first choice for professional repair benches worldwide.

  • Flawless Round Seating: Drastically improves tuning recovery during heavy string bending, vibrato, or tremolo system usage.

Workshop Handling Notice: Ultra-thin files (especially the .010" and .013") feature extremely thin, flexible metal bodies. Always apply light, linear downward pressure without lateral force to avoid bending or breaking the file during operation.

Frequently Asked Questions

Can I use these files to cut slots into metal nuts, such as brass or steel?
No. These files are specifically engineered for organic and composite materials like bone, horn, wood, and hard plastics. Attempting to file brass, steel, or titanium will prematurely dull the precision teeth and ruin the tool.

Why are there 8 files if a standard guitar only has 6 strings?
The 8-piece set provides highly versatile combinations. For instance, the extra steps allow you to choose between standard light electric strings (.010 to .046) or medium-gauge strings/acoustic low ends up to a .056, making this a true universal bench setup kit.

How should I maintain my Hiroshima nut files?
Keep the teeth free from packed bone dust or plastic residue by cleaning them periodically during use with a soft brass file brush. Store them in individual slots inside a tool wrap or case to prevent the files from rubbing against one another.
