Perma-Grit Contour Sanding Block Large 280 x 51mm

Large version (280mm x 51mm) of the ultra useful Perma-Grit double sided tungsten carbide contour sanding block. The abrasive faces measure 28mm Radius internal face and 30mm Radius external face. Ideal for finishing under cambers, grooves and fillets. Leading and trailing edges.

The quality of the tungsten carbide strips means that they will shape carbon fibre without the characteristic 'fraying' associated with conventional sandpaper or wet-and-dry. The abrasive will also not 'lose its edge' or fall apart meaning a sanding block can last you for years!

The faces are both fine grit, equivalent to 320 grit sandpaper. We also stock large 'standard' or 'wedge' sanding blocks.

Typical uses

How to Use

Hold the sanding block comfortably in one hand and gently use it to shape, bevel or smooth the piece of carbon you are working. Always work from a course grit to a fine grit before moving on to a rubbing compound and finally wax.

Unclog the abrasive strip with a fine wire brush to keep it working at its most effective. Clean with a solvent such as Acetone if necessary.

We also stock a small contour sanding block measuring 140 x 51mm, should that suit your particular project.
