Walter 2.5 Inch Mini Flap Disc 40 Grit Type R Mount

Master Tight Spaces with Walter Mini Flap Discs

For professional welders, finishing a weld in a tight corner or inside a small diameter pipe has always been a challenge. The Walter 2-1/2" Flap Disc with 40 Grit abrasive is the solution you have been looking for. This pack of 5 discs is designed to turn your die grinder into a powerful finishing tool, allowing you to blend welds and smooth surfaces in areas that a standard angle grinder can't touch. The coarse 40 grit is aggressive enough to knock down TIG welds or smooth out MIG beads quickly, leaving a clean surface ready for painting or further polishing.

The convenience of the Type R (TR) mounting system cannot be overstated. When you are in the middle of a job, you don't want to hunt for tools to change your abrasive. The plastic TR button on the back of these discs allows for a secure, spin-on connection that holds tight during operation but releases easily by hand when it's time to swap out. This system ensures that the disc remains centered and balanced, reducing vibration and operator fatigue during extended use. It is the perfect companion for detail work on custom railings, automotive exhaust systems, and precision machinery.

Walter Surface Technologies is known for producing abrasives that work as hard as you do. These mini flap discs are no exception, offering remarkable durability that outlasts standard sanding discs. The layered flap design runs cooler than solid grinding wheels, which helps prevent heat discoloration on heat-sensitive materials like stainless steel. By combining the aggressiveness of a grinding wheel with the blending capability of a fiber disc, this product allows you to achieve a finished surface in fewer steps. Whether you are working with aluminum, steel, or stainless, these discs deliver professional results every time.
