Avora Industrial premium zirconia flexible flap disc grinding wheels are manufactured with premium zirconia. Ideal for hard to reach places, organic shapes and contoured surfaces our flexible flap discs make short work of the hard to reach spots other discs and grinding wheels won't go. Avora Industrial's scientifically engineered constant particle size and formulated ingredients make a proven superior product. Our zirconia abrasive grains are essentially equal in size and structure and are thus more aggressive, more responsive and longer lasting. Premium zirconia offers very high wear resistance. When high strength and low propensity for contamination are required our zirconia performs exceptionally well. It resists break down at high temperature or under high pressure thus it securely maintains its structure and thus its performance. Our premium zirconia material is bonded with a resin to a poly / cotton backing. This resin bond and poly / cotton fabric combination allow for high efficiency and high material removal capacity. They have greater edge strength and longevity due to low stretch, high strength properties. Add to that high concentrations of premium zirconia alumina abrasive media and this product becomes very hard to beat. Avora premium zirconia wheel construction has as much as 50% more media per flap when compared to other competing products. Feel comfortable using our products knowing they are subjected to numerous performance and safety tests to ensure their quality and safety. We believe with the right tools, time, know-how and budget we can build anything. The future is bright. Come build with us. Put Avora Industrial's materials to good use.
