Frequently Asked Questions

What are the key specifications and advantages of these 5-inch ceramic alumina discs?
These discs feature a 5-inch diameter with a durable fibre backing and a 80-grit ceramic alumina abrasive. The ceramic alumina grain is engineered to stay sharper longer than conventional aluminum oxide, providing a faster cut rate and longer life on tough materials like metal and hardwoods.
What are the primary applications or recommended use cases for these 80-grit sanding discs?
This 80-grit is ideal for aggressive stock removal and heavy-duty shaping on materials like steel, aluminum, welded seams, and hardwoods. The fibre backing provides the flexibility needed for contour sanding, making them suitable for both metal fabrication and woodworking applications requiring a coarse, fast-cutting action.
How are these discs packaged and what is the minimum order quantity?
The discs are packaged 20 per box. Each disc has a standard center hole for secure attachment to a 5/8-inch-11 threaded backing pad, which is common for most right-angle grinders and sanders.
