Siafast Velcro Disc 150mm, P180 grit.
Siafast hook and loop sanding discs for random orbit and orbital sanders, made in Switzerland by sia Abrasives. Coarse grits use a sharp ceramic and aluminium oxide blend for fast cutting; P100 and finer use blue-fired aluminium oxide for long life and an even scratch pattern. Stearate open coat resists clogging on paint, filler and primer as well as bare timber.
Match the hole pattern to the sander and work through the grits.
