XL Interchangeable Fingerboard Radius Insert

The XL interchangeable radius sanding insert is ideal for accurately sanding guitar and bass fretboards, whether you are working on a six-string guitar or an eight-string bass. Designed to fit our ergonomic holder perfectly, these inserts provide clean, even sanding whatever radius you choose.

3D-printed in our workshop, each XL interchangeable radius insert provides a precisely calibrated sanding surface. Available in several standard and custom radii, they allow accurate work on all types of fretboard. Their sturdy design ensures that abrasive paper stays firmly attached with double-sided tape.

The inserts attach to the holder using two screws and wing nuts, allowing quick, intuitive changes without complicated tools. This practical system makes it easy to switch from one radius to another according to your project. To use these inserts, you must have the XL guitar radius sanding block from our catalogue.

Although visible layer or machining marks may appear as a result of 3D printing, sanding quality remains excellent thanks to the precise design and even support for the abrasive. These inserts combine precision, comfort and ease of use for guitar-making enthusiasts.
