Two-Way Radius Sanding Block for Fret Leveling - Dual 7.25/15 Radius

In this review the Two-Way Radius Sanding Block for Fret Leveling proves to be a practical, purpose-built tool for luthiers and hobbyists who need a reliable sanding beam. Its single biggest reason to buy is the dual-radius design that covers the two most common fretboard arcs, making it a compact, time-saving addition to a repair bench. The block's CNC-machined aluminum body gives it noticeable weight and solidity, and while sandpaper must be supplied separately, the tool itself simplifies fret leveling and fingerboard maintenance.

Key Features

• Dual radius design: Two built-in radiuses, 7.25 and 15, let one block handle the most common guitar and bass fingerboard arcs without swapping tools.
• CNC-machined aluminum body: A machined metal construction offers rigidity and resistance to deforming, so the block keeps its shape under repeated use.
• Grooved grip: The groove side provides a comfortable, non-slip hold for controlled sanding across the fingerboard.
• Convenient dimensions: At roughly 200mm long it spans most fretboards for even sanding while remaining easy to maneuver on shorter instruments.
• Two-way operation: Each face presents a different radius so the same tool can be flipped for the alternate arc, reducing clutter in the workshop.

Who It's For

This sanding block is best for working luthiers, technicians, and experienced hobbyists who perform routine fret leveling or fingerboard flattening on guitars and basses. Those who regularly switch between instruments will appreciate the two-radius convenience and the block's weight for steady control.

It is not aimed at someone who needs every possible radius size or expects an all-in-one kit; sandpaper is not included and different instruments may require different arcs, so beginners should confirm their instrument's radius before purchase or consider a set with more radius options.

Pros & Cons

Pros

• Durable CNC-machined aluminum construction provides a confident, solid feel during use.
• Two common radiuses in one block save time and space on the workbench.
• The grooved grip enhances handling and control while sanding.

Cons

• Sandpaper is not included, so you must supply abrasive strips cut to size.
• Only two radiuses are offered; shops needing other arcs will require additional blocks.
