The 150mm 40 Grit Zirconia Velcro Sanding Discs (8356) are high-performance abrasives engineered for aggressive material removal and long service life. Made with premium zirconia abrasive grains, these discs deliver fast, consistent cutting power — ideal for heavy-duty sanding, grinding, and surface preparation.
Featuring a hook-and-loop (Velcro) backing, they attach securely to orbital sanders for quick disc changes and reliable grip during operation. The coarse 40-grit finish makes them perfect for removing rust, paint, and welds on metal, as well as for shaping and rough sanding wood and composites.
