This 320 grit variant offers ultra-fine finishing capabilities, ideal for achieving exceptionally smooth surfaces prior to final coating or for polishing applications. The 320g rating on these 150mm discs makes them perfect for delicate finishing work where minimal material removal and maximum surface refinement are required. Manufactured from aluminium oxide with a special calcium stearate treatment, resin bonded to provide self-sharpening action and anti-clogging performance, these discs deliver consistent results even during prolonged use. The heavy-duty D-Weight backing paper construction provides durability to handle tough materials, whilst the hook and loop backing ensures secure attachment and facilitates quick disc changes. Six pre-punched 8mm holes optimise dust extraction performance, maintaining a clean work surface and improved visibility. Supplied in packs of 10 discs, these professional-grade sanding discs are compatible with all 150mm random orbit sanders featuring hook and loop backing pads, including Draper models 65084, 83942 and 84125.
