This kit makes dust free sanding a reality, containing everything you need except a vacuum extractor. It comprises a Mirka hand sanding block, 70 x 125mm, hose and a variety of Abranet abrasive sheets to suit. The hand sanding block has a velcro-style base to secure the abrasive. It is light in weight and very comfortable to hold. The 20mm x 4m hose fits directly onto the Mirka hand sanding block. At the opposite end a universal cone shaped fitting enables connection to many vacuum type extractors. The Abranet abrasive guarantees dust free sanding without clogging. This open mesh features thousands of tiny holes which ensure the passage of dust will be incredibly efficient. Using the vacuum system keeps the surface that you are sanding dust free resulting in an ultra smooth finish. In addition to the sanding block and hose, the kit contains 250 sheets of Abranet (50 of each: 120g, 180g, 240g, 320g and 400g).
