09D503 - Walter 3-Inch Spinlock Zirconia Grinding Disc 36 Grit

High-Efficiency Material Removal in Confined Spaces

The Walter Spinlock Z/A Resin Fiber Disc (SKU: 09D503) represents a pinnacle in small-diameter abrasive technology, designed specifically for industrial environments where precision and speed are paramount. Engineered by Walter Surface Technologies, this 3-inch disc utilizes a premium Zirconia Alumina (Z/A) grain structure. Zirconia Alumina is renowned in the metallurgical finishing industry for its self-sharpening properties and high fracture toughness, allowing the abrasive to maintain a sharp cutting edge throughout its service life. This results in a consistent material removal rate (MRR) that outperforms standard aluminum oxide discs, particularly in high-pressure applications.

The defining feature of this product is the Spinlock fastening system, which is compatible with industry-standard Type R (plastic button) quick-change backing pads. This mechanical interface eliminates the need for locking nuts and wrenches, facilitating rapid changeovers that significantly reduce non-value-added time during multi-step finishing processes. For maintenance, repair, and operations (MRO) professionals, this translates to higher throughput and reduced labor costs.

At a coarse 36 grit, this disc is optimized for heavy stock removal, weld leveling, and surface preparation. The resin fiber backing provides the necessary rigidity to withstand the torque of high-speed die grinders while offering enough flexibility to contour slightly to the workpiece. It is chemically designed to minimize heat generation, making it an excellent choice for working with heat-sensitive alloys like stainless steel and aluminum, preventing thermal deformation or discoloration.

Key Technical Benefits:

• Zirconia Grain: Delivers faster cut rates and longer life than conventional abrasives.
• Thermal Management: Cool cutting action preserves the metallurgical integrity of the substrate.
• System Compatibility: Fits standard Type R backing pads for seamless integration into existing tool cribs.
