Fret Crowning - with the advantage of polishing frets using the same abrasive!. The tool doesn't chatter and restores roundness without touching the top of the fret.


The underside of the tool is concave with a gap at the centre. When pressure is applied, the sides of the fret are rounded but the abrasive avoids contact with the very top of the fret. This design feature allows the tool to be used on narrow to medium fretwire. The ideal range for the tool is from 0.095" (2.4mm) up to 0.105" (2.7mm).



With its inherent polishing capability, emery is the preferred abrasive for final finishing and lapping of metal surfaces requiring high precision and smooth surface finish.
