Product Features:
High-Quality Aluminum Oxide: A tough, durable grain that provides a consistent finish and steady material removal rate for general metalworking projects.
Heavy-Duty Vulcanized Fibre Backing: Offers the necessary rigidity and strength to withstand high-pressure grinding while resisting tearing and warping.
Resin-over-Resin Bond: Features a high-strength resin bond that firmly secures the grain to the backing, ensuring better grain retention and heat resistance during use.
Versatile Application: The ideal "all-around" disc for shops working with mild steel, wood, or plastics where the extreme cost of ceramic or zirconia isn't required.
Available Grits:
24 – 36 Grit: Best for initial grinding, heavy rust removal, and leveling small weld beads.
50 – 60 Grit: Ideal for general blending, deburring, and breaking down sharp edges.
80 Grit: Perfect for surface cleaning, light blending, and removing surface imperfections.
100 – 120 Grit: The choice for fine finishing, removing scratches, and prepping surfaces for paint or primer.
