Features and Specifications

- Size: 6 inch (150 mm) with 81 holes for dust extraction
- Grain: aluminum oxide
- Backing: FSC-certified paper, open electrostatic coat
- Bond: resin over resin
- Top coat: stearate, which resists clogging and helps the disc last longer
- Pack: 100 discs per box
Where 320 Grit Fits
Use 320 after 220 or 240 on primer, and for sanding between coats of lacquer or paint. Follow with 400 or 500 when the next coat calls for a finer scratch.
Who Uses It
Automotive refinishers, collision shops, furniture and cabinet shops and industrial finishing lines use the Sia 8443.7842.0320 on body filler, primer filler, lacquers and paints. The 81-hole pattern pairs with multi-hole 6 inch pads and dust extraction to keep the surface clear while you sand.
Tips for Longer Disc Life
Use light, even pressure and let the abrasive cut. Keep the pad flat to avoid rounding edges, and clean the surface between grits so loose particles from a coarser step do not leave stray scratches. Change the disc as soon as it stops cutting; a worn disc only polishes and builds heat. Store boxes flat in a dry place so the paper stays flat.
