This product is a high-performance louvered pure wool polishing wheel (115mm/4.5 inches) designed for fine polishing of metal, glass, stone, and precision instrument surfaces. It uses high-quality compressed wool felt as the abrasive base, secured to a reinforced fiber backing via a fan-shaped, overlapping "louver" structure. This unique design allows it to be mounted on a standard angle grinder, providing a more efficient, cleaner, and longer-lasting polishing experience than ordinary flat wool wheels, making it ideal for achieving a mirror finish.

1. Innovative Louvered Structure Design
   High-Efficiency Heat Dissipation:

   The overlapping fan-shaped structure generates airflow during high-speed rotation, effectively reducing heat buildup on the workpiece surface and preventing material damage or discoloration due to overheating.

   Excellent Flexibility:

   The louvered structure gives the polishing wheel a certain degree of elasticity, allowing it to better conform to the curved surfaces and uneven areas of irregular workpieces, achieving polishing without dead angles.

2. Premium Pure Wool Material
   Mirror Finish Effect:

   Made with high-density fine wool, the soft and elastic texture, when used with polishing compound, quickly removes minor scratches, significantly improving surface brightness and gloss.

   Protecting the Substrate:

   Compared to hard abrasives, wool felt polishing wheels are gentler and will not leave secondary scratches on the workpiece surface, ensuring consistent polishing quality.

3. Durability and Safety
   Extra-Long Lifespan:

   As the outer layer of wool is consumed, the underlying wool is continuously exposed for operation, resulting in extremely high utilization and a longer lifespan than traditional flat-pressure wool wheels.

   Sturdy Backrest:

   Features a reinforced fiber cover (black disc section) and a stainless steel center ring, ensuring safety and stability during high-speed angle grinder operation, preventing vibration, and reducing operator fatigue.

4. Wide Application Compatibility
   Standard Size:

   115mm outer diameter, suitable for most small and medium-sized angle grinders on the market, with simple and quick installation.

   Multi-Material Compatibility:

   Widely used in stainless steel polishing, mold making, automotive detailing, marble restoration, and fine polishing of various jewelry and jade items.

It is recommended to use with appropriate polishing pastes (such as blue, purple, or white polishing sticks) to achieve the best mirror finish.

When polishing, please control the angle grinder speed within a reasonable range to avoid carbonizing the wool or splattering of the polishing paste due to excessive speed.
