Walter 3-Inch Spinlock Resin Fiber Sanding Disc 36 Grit

Precision Weld Blending and Finishing

For welders and fabricators, the finish is just as important as the weld itself. The Walter Spinlock A/O Resin Fiber Disc, 3" G36 (09D203), provides the aggressive cutting power needed to tackle tough weld seams while offering the control required for detailed work. This abrasive disc utilizes high-quality Aluminum Oxide grains bonded to a durable fiber backing, ensuring it stands up to the heat and pressure of grinding down bead profiles and heavy slag.

The 36 grit classification places this disc in the coarse category, making it the go-to choice for the initial stages of post-weld cleanup. It rapidly removes excess material, allowing you to shape the metal quickly before moving to finer grits for polishing. The 3-inch diameter is specifically advantageous for automotive exhaust work, roll cage fabrication, and intricate architectural metalwork where standard angle grinders are too bulky. The smaller footprint allows for focused grinding without gouging adjacent surfaces.

Compatibility is key in a welding shop, and the Spinlock system integrates seamlessly with standard die grinders and right-angle drills using the appropriate backing pad. This quick-change capability means you can swap from a grinding disc to a conditioning disc without reaching for a wrench, keeping your workflow smooth and uninterrupted. Safe for use on stainless steel and aluminum, this disc is formulated to minimize contamination, helping you maintain the integrity of your base materials.
