The high concentration of diamonds provides faster cutting speed, while the high quality of diamonds provides longer blade life. It has passed EN13236 test to achieve the best grinding effect at the highest speed up to 12,250 rpm. Special design: professional tools with excellent cost performance due to the use of high-quality, high-temperature-resistant diamonds are resistant to impact and high temperatures and reduce vibration through use of precision tool holders, are more efficient and durable. Grinding segments with heat-treated steel body that increase the durability and life of the grinding wheel. Ventilation holes for fast, dry or wet grinding with long life. Wheels for angle grinders, used in concrete, marble, granite, adobe, gypsum sandstone, natural slate sandstone, artificial and natural stone, masonry, screed.< /p> These are high quality disc grinders, suitable for sanding marble, ceramic tiles, concrete and rocks. High concentration of diamond can improve durability and effectively remove roughness. Our segmented grinders are suitable for grinders, angle grinders, etc. This wet/dry diamond wheel is ideal for fine grinding, creating surface patterns and shaping corners and edges. Diamond wheels are ideal for rapid grinding of concrete, masonry, stone and other masonry products. The wear-resistant metal bond is combined with diamond, and its particle size and concentration are specially designed to be suitable for grinding. This is an effective way to remove material and extend life! The cutting wheels are specially designed for angle grinders, concrete sanders, concrete sanders, wall sanding systems and floor sanders. The cutting discs use diamonds that are extremely resistant to impact and high temperatures - they are perfectly combined with wear-resistant metal connections. Feature: Type: Diamond grinding wheel Working materials: concrete, lightweight concrete, granite, artificial and natural stone, floor slab Diameter: 125 mm Hole: 22.23 mm Multiple uses You can safely and reliably handle concrete, concrete products, screeds, granite, natural stone, stone, masonry and other materials. Diamond grinding wheels are used not for cutting, but for high-quality processing of concrete products and natural and artificial stones by grinding.you can not only remove a uniform layer of material, but you can also create grooves in concrete and stone to install equipment or other elements.
