09D108 - Walter 2-Inch Spinlock Aluminum Oxide Sanding Disc 80 Grit

Professional Grade Small Diameter Finishing

The Walter Spinlock A/O Resin Fiber Disc (SKU: 09D108) represents a high-efficiency solution for metal fabrication professionals requiring precision and speed in confined spaces. Engineered with a premium Aluminum Oxide (A/O) grain structure, this 2-inch disc delivers a consistent cut rate and uniform finish, making it an essential consumable for MRO (Maintenance, Repair, and Operations) environments and industrial fabrication shops. The 80-grit composition is specifically selected to bridge the gap between aggressive material removal and surface preparation, allowing operators to blend welds and remove imperfections without gouging the base material.

Central to this product's utility is the Spinlock™ quick-change attachment system. In high-throughput operations, the time spent changing spent abrasives can accumulate significantly. The Spinlock mechanism allows for tool-free mounting and dismounting with a simple twist, ensuring that the disc is securely centered and locked during high-RPM operation. This positive locking mechanism minimizes vibration, which not only extends the life of the abrasive by preventing edge-chipping but also reduces mechanical stress on the power tool's bearings and the operator's hands.

The resin fiber backing provides the necessary rigidity to withstand the torque of pneumatic die grinders while retaining enough flexibility to conform to slight contours. This balance is critical when working on complex geometries often found in automotive repair, aerospace component finishing, and general machinery maintenance. Compatible with mild steel, stainless steel, and aluminum, this disc eliminates the need for multiple inventory items for different substrates in general-purpose applications. Whether used for cleaning gasket surfaces, blending spot welds, or deburring machined parts, the Walter 09D108 delivers reliable, professional results.

Technical Application & Compatibility

Designed for use with standard backing pads compatible with the Spinlock/Type R fastening system, this disc integrates seamlessly into existing tooling setups. The Aluminum Oxide grain is resin-bonded to ensure grain retention under thermal stress, preventing premature glazing. For optimal performance, it is recommended to operate these discs at the manufacturer's suggested RPM range, ensuring the abrasive fractures correctly to expose new sharp edges, maintaining a consistent cut throughout the disc's lifecycle.
