Fret Crowning Gauge Set for Guitar, Bass and Ukulele A practical tool set for reshaping and finishing frets. Designed to make fret crowning and edge work faster and more consistent while remaining simple to use. Key benefits Accurate fret shaping: Four gauge slots in 1mm, 2mm, 3mm, and 4mm let you match common fret widths for consistent crowning. Saves time: Diamond abrasive surfaces provide efficient material removal for quick reshaping and dressing. Complete fret edge work: Includes one flat file for cleaning and rounding fret ends and smoothing fret edges. Smooth finish workflow: Diamond abrasive is effective for initial shaping but can be coarse for final polishing; use fret erasers or fine polishing tools after crowning to achieve a smooth, playingready surface. Versatile compatibility: Suitable for electric guitar, acoustic guitar, bass, ukulele, and other fretted instruments. Features and specifications Gauge slots: 1mm, 2mm, 3mm, 4mm to accommodate different fret sizes. Abrasive type: Diamond abrasive for fast, durable cutting and shaping. Included tool: One flat file for fret edge and fret end rounding. Use cases: Crowning worn frets, preparing frets after levelling, cleaning fret ends after refretting. How it solves common problems Restores fret profile: Quickly recovers rounded fret crowns after leveling or wear, improving intonation and playability. Controls fret width: The four gauge sizes help you choose the right profile for each fret to avoid overcutting. Simplifies edge work: The flat file helps remove sharp edges and round fret ends without removing excess material from the crown. Improves workflow: Use the diamond abrasive for shaping and follow with fret erasers for polishing to achieve a smooth surface and reduce string buzz. Practical use scenarios Electric guitar setup: After leveling frets during a setup, use the appropriate gauge slot to recrown frets and the flat file to round fret ends for comfortable play. Acoustic guitar maintenance: Recrown frets that show wear from frequent play to restore note clarity and sustain. Bass or ukulele : Dress and shape wider or narrower frets using the 3mm and 1mm slots respectively, and polish with fret erasers for a smooth finish. Tips for results Start with the diamond abrasive to reshape and define the crown, using light, controlled passes. Always follow with finer abrasives or fret erasers to remove diamond scratching and achieve a polished surface. Choose the gauge that most closely matches the existing fret width to preserve fret life and avoid overcutting. Work gradually and check fret height and playability frequently. This fret crowning gauge set offers a straightforward, effective method for reshaping frets and finishing edges on a wide range of fretted instruments.
