High-Performance eXtreme Resin Fiber Discs – 4-1/2" x 7/8", Un-Hubbed

This 4-1/2" un-hubbed Resin Fiber Discs is engineered for enhanced durability and high-efficiency cutting. The unique treatment process increases grain hardness, providing consistent cutting action and faster material removal, even under heavy pressure. The high-performance grain reduces heat buildup, minimizes clogging, and boosts productivity in tough grinding and sanding applications. Ideal for hard metals, stainless steel, and other demanding materials, this wheel is perfect for industrial and heavy-duty applications. Rated for a maximum speed of 13,300 RPM with a 24-grit construction, it delivers reliable, long-lasting performance.
