RBX Cloth - The General Purpose All Rounder Abrasive

Tax included Shipping calculated at checkout.

RBX - GXK51 Aluminium Oxide

A very good all round general purpose sanding belt for both wood and steel for both stock removal and finish sanding.

It is by far the most commonly used abrasive available, particularly for pre-made portable belts. It is easily distinguished by its brown or reddish brown colour and will be found in every hardware shop that sells sanding and linishing belts.

GXK51 Aluminium Oxide is a Resin Coated, Closed Coat Abrasive on X Weight Cloth backing.

A very cost effective option, but does not have the longevity of other mediums.

Available grits:

40, 60, 80, 100, 120, 150, 180, 240, 320 & 400

Ideal For:

Sanding / Grinding metal and wood
