Professional quality 178mm Zirconia Sanding Discs designed for fast, aggressive sanding and long-lasting performance on wood flooring and hardwood surfaces. Each disc features a precision 22mm centre hole for secure fitting and compatibility with most edger sanding machines, helping ensure smooth operation, improved dust extraction, and stable sanding performance.
Manufactured using premium zirconia abrasive grain, these sanding discs provide superior cutting power and durability compared to standard aluminium oxide abrasives. Zirconia abrasives are self-sharpening, meaning the abrasive grains continuously fracture during use to expose fresh cutting edges, maintaining an aggressive cut and extending the lifespan of the disc. This makes them ideal for heavy-duty floor sanding, edge sanding, hardwood preparation, and rapid material removal.
The heavy-duty backing offers excellent tear resistance and reliability under demanding sanding conditions, while the open-coat design helps minimise clogging and heat build-up for smoother, more efficient sanding. Zirconia discs are especially effective on hardwood floors, parquet flooring, painted surfaces, and tough coatings where consistent cutting performance is essential.
