09D205 - Walter 3-Inch Aluminum Oxide Quick-Change Sanding Disc Grit 50

Precision Abrasive Performance for Confined Spaces

The Walter Spinlock A/O Resin Fiber Disc (SKU: 09D205) represents a high-performance solution for industrial surface finishing and material removal in restricted areas. Engineered with a premium Aluminum Oxide (A/O) grain structure, this 3-inch disc is designed to deliver a consistent cut rate and a uniform scratch pattern throughout its lifespan. The resin fiber construction provides the necessary rigidity and backing strength to withstand the mechanical stresses of aggressive grinding while maintaining flexibility for contour work.

Central to this product's efficiency is the Spinlock quick-change attachment system. In high-throughput industrial environments, downtime associated with abrasive changeovers can significantly impact overall productivity. The Spinlock mechanism allows operators to switch discs in seconds with a simple twist-on, twist-off motion, ensuring that the tool spends more time in contact with the workpiece. This system also ensures a centered, vibration-free mount, which is critical for maintaining precision and reducing operator fatigue during extended use.

The Grit 50 specification places this disc in the coarse-to-medium range, making it exceptionally suitable for applications requiring moderate stock removal, weld leveling, and surface preparation. It effectively bridges the gap between heavy grinding and fine finishing. The aluminum oxide grain is friable enough to self-sharpen, yet tough enough to resist premature dulling when working on carbon steel, stainless steel, and aluminum alloys. This versatility allows MRO professionals to consolidate inventory by using a single disc type for multiple substrate materials.

Furthermore, the disc incorporates cool-cutting technology to mitigate the risk of thermal distortion or discoloration, particularly on heat-sensitive materials like stainless steel. By reducing heat generation at the point of contact, the Walter Spinlock disc preserves the metallurgical integrity of the base material. Whether utilized for automotive repair, aerospace component finishing, or general metal fabrication, this abrasive tool delivers the reliability and performance expected from Walter Surface Technologies.
