These 200mm, 40 grit sanding discs are produced from aluminium oxide which is resin-bonded for longer life and to provide anti-static, improved grain adhesion. The heavy duty E-weight backing paper enhances performance, with the sanding disc more durable and able to withstand the toughest of jobs. Hook and loop backing promotes good adhesion and enables quick disc change. The discs are suitable for sanding and finishing on wood, metal, aluminium alloy, painted services, plastics and fillers. They are compatible with all 200mm bench sanders with a hook and loop backing, including Draper�s 230V Belt and Disc Sander (Stock No. 98525). The discs are supplied in a pack of 10.
