The type of abrasive recommended & supplied with the kit is Emery Corundum - less aggressive than diamond - but with excellent polishing characteristics. It is recognised as the best abrasive for finishing and polishing of metal which makes it a perfect choice for fret crowning and fret dressing. 

Genuine Emery Corundum is made from crushed Emery Stone - Rich in Blue Corundum/Blue Sapphire. Its composition enables a highly polished finish to be achieved.


Dependant on fret wear, the abrasive included is sufficient for 4-6 fretting jobs, however as the emery becomes smoother with use, the abrasive should not be discarded too soon as it can be retained for lighter work.


2 options of Spare Fret Levelling Abrasive can be purchased from the Webstore:

Coarse - Smooth - Fine (Heavy wear)

Smooth - Fine (Light wear)


Spare Fret Crowning Abrasive is also available.
