Luthier Tool - Fret Leveller

A versatile precision Fret Leveling Tool with more than one use!.

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. Emery is less aggressive than diamond - but has inherent polishing characteristics. It is acknowledged as the best abrasive for finishing and polishing of special metals by engineers and jewellery makers.

Our Fret Levelling Tool has an ergonomic shaped handle with a recess for the thumb at the leading end and an angled back for good control with 2-handed use.

Fret Levelling Accuracy | GMC Luthier Tools



The guitar neck should be set straight before levelling the frets. It is recommended to utilise a Notched Straight Edge for this purpose as this will reference the fretboard surface itself and ensure consistency of the finished fret profiles and playing feel along the board.


The frets should ideally be fully masked to ensure the fingerboard wood is completely protected. Controls and hardware should be protected from dust also. If the guitar has a natural finish or is open grained then extra care should also be taken. All dust should be thoroughly cleaned before removing any masking.

What Fret Levelling Abrasive should I use?

The starting fret levelling abrasive grade will be dependent on the degree of fret wear. 

Coarse, Smooth & Fine grades are supplied with the Fret Leveller making it suitable for heavier wear and guitar shop use.

Smooth Abrasive then Fine is recommended for guitarists performing their own guitar setups.

After levelling, the frets will require crowning to achieve a satisfactory playing feel and to optimise intonation.

Replacement fret levelling abrasive can be purchased from the webstore in convenient pre-cut strips. The fret leveller will also accept 25mm standard width roll. 



The tool is also useful for detail sanding/flat sanding of wood by incorporating a suitable abrasive.

(Emery supplied with the tool is not suitable for use on wood).
