09D408 - Walter 2-Inch Spinlock Zirconia Sanding Disc 80 Grit

High-Performance Small Diameter Abrasive Solutions

The Walter Spinlock Z/A Resin Fiber Disc (SKU: 09D408) represents a pinnacle in small-diameter abrasive technology, specifically engineered for precision surface finishing in industrial environments. Designed to address the challenges of accessing restricted spaces without compromising on material removal rates, this 2-inch disc utilizes a premium Zirconia Alumina (Z/A) grain structure. Zirconia Alumina is renowned in the abrasives industry for its self-sharpening properties and durability under high pressure, making it an optimal choice for demanding applications on carbon steel, stainless steel, and aluminum substrates.

Efficiency in Maintenance, Repair, and Operations (MRO) often hinges on tool changeover times and abrasive longevity. The Spinlock fastening system integrated into this disc features a plastic "TR" button, compatible with standard Type R quick-change backing pads. This mechanism ensures a secure, vibration-free connection that can be engaged or disengaged in seconds, significantly reducing downtime during multi-step finishing processes. The resin fiber backing provides a rigid yet flexible foundation, allowing the abrasive grains to fracture optimally and maintain a consistent cut rate throughout the product's lifespan.

With an 80-grit profile, this specific model serves as an excellent intermediate abrasive. It is sufficiently aggressive to blend light welds and remove surface imperfections while leaving a finish that prepares the workpiece for final polishing or coating. The thermal stability of the resin bonding system aids in cool cutting, mitigating the risk of heat discoloration on heat-sensitive alloys like stainless steel. For industrial procurement specialists seeking reliable, high-throughput abrasive consumables for die grinders and right-angle air tools, the Walter Spinlock Z/A series delivers consistent, measurable performance.

Technical Application Scope

This abrasive disc is best utilized in fabrication shops, aerospace maintenance, and automotive manufacturing where precision in small areas is critical. It excels in deburring machined parts, blending pit marks, and cleaning metal surfaces prior to welding. The 2-inch footprint allows operators to maneuver within channels, pipe interiors, and complex geometries that larger 4.5-inch or 5-inch discs cannot reach.
