These high performance sanding belts (13 x 457mm) are made from aluminium oxide that is resin bonded to provide efficient resistance and long lasting performance. The electrostatic sand planting and open coat aluminium oxide grain are useful for chip removal and heat dissipation. The special butt joint minimises the effect of vibration across the work surface ensuring a smooth and even finish. The strong X-weight polycotton cloth backing makes the sanding belt both flexible and durable, enhancing the intensity of loading and enabling it to be used in different pressure applications. Ideal for sanding and finishing wood, metal, aluminium alloy, painted surfaces, plastic and fillers. Compatible with all 13 x 457mm sanders.
