30-Pack Dual Grit Combination Discs (40 & 60 Grit) – This 4 1/2-inch flap disc set contains 15 discs with 40 grit and 15 discs with 60 grit. The 40 grit is perfect for aggressive material removal, rust removal, and weld smoothing, while the 60 grit allows for efficient material removal and a smoother surface finish. A versatile combination for various sanding and finishing stages.

High-Quality Zirconia Corundum for Durability – Made from high-quality zirconia corundum abrasives, these sanding discs are more wear-resistant and durable than traditional alumina.

They also retain their sharpness and cutting ability even under high temperatures and pressures, ensuring a long service life and cost-effective operation. T29 Conical Design for Contour Grinding – The angled T29 design allows the disc to work efficiently on edges, corners, and curved surfaces. Ideal for edge grinding, degreasing, weld smoothing, and round grinding. It offers greater flexibility and precision for applications with a recommended working angle of 5 to 15°. Reinforced Fiberglass Backing Plate – The high-strength fiberglass backing plate on this angle grinder disc effectively absorbs vibration, increases operating stability, and prevents cracking or delamination. This results in more even sanding, better control, and a cleaner, contaminant-free work surface. Wide compatibility and versatile material application – With a 4 1/2-inch diameter and a 7/8-inch shank, 4 1/2-inch flap discs are compatible with most standard angle grinders and support speeds up to 13,300 RPM. Suitable for metal, wood, plastic, fiberglass, and rubber – ideal for sanding, smoothing, refining, and finishing a variety of materials and projects.
