2、Wear Resistance: Because the structure of the grinding wheel is combined with a special synthetic resin, the wheel can strengthen its wear resistance and grinding force, and because of the existence of special pores in the grinding wheel structure, it can quickly remove abrasive debris, avoid plugging and heat generation. Suitable for long-term grinding work.
3、Wide Application: The sponge wheel is suitable for grinding stainless steel, aluminum, copper, iron, touch, wood, gemstone, marble, glass, bakelite, urea products, leather, etc. It is suitable for stainless steel, clocks, jewelry, glass and stone industries.
