One of the advantages of the grinding wheel PS 33 BK from Klingspor is that it is easy to attach to the sanding device as it is Velcro. The grinding wheels are easy to press on on sanding devices with Velcro sanding surface and a firm hold is guaranteed due to the flexible barbs. Thanks to this Velcro fastening, the sanding disc is always smooth and straight. The PS 33 BK is the right choice for sanding paint, varnish, filler and wood. The discs are available in different sizes and without holes or with different sized holes, as Klingspor also has the right model for all standard sanding devices. A selection of different grits is also available for processing the different materials. Corundum in semi-open scattering type - grinding wheel for versatile applications. The material of the abrasive grain is crucial for material removal when grinding. Modern abrasives are coated with particularly durable and efficient synthetic grain types and are also of varying hardness and toughness. The grain is made of corundum, a particularly hard and tough material. Corundum is characterised by its crystalline properties and irregular shapes, allowing a high removal rate. The grain is applied in semi-open scattering density and therefore ideal for sanding paint and varnish. Thanks to the larger chip space, the abrasive dust can escape and does not settle on the grinding wheel PS 33 BK, so that clogging is prevented. This contributes to a longer life of the sanding disc. PS 33 BK sanding disc on paper backing (B-paper) with synthetic resin binding. The PS 33 BK is based on a paper backing (B-paper) and ideal for use when surface sanding. The B paper is easy to cut, tear and bend, so that this sanding disc is also suitable for hand sanding in hard-to-reach places when there is no specially designed sandpaper at hand. The resin bonding contributes to the reliable attachment and embedding of the grain. On the PS 33 BK sanding disc the grain is first attached to the paper base with resin and then covered with a resin cover binding. This means that the grains are safely and firmly embedded. The resin on the surfaces of the grains will rub off on the first cut.
