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 12250rpm. Special design: the professional tools with excellent cost performance due to the use of high-quality, high-temperature resistant diamonds resist shock and high temperature and reduce vibration through the use of precision tool holders, more efficient and durable. < p>Grinding segments with heat-treated steel body that increase the durability and life of the grinding wheel. Venting holes for fast, dry or wet grinding with long life.< /p> Wheels for angle grinders, used in concrete, marble, granite, adobe, gypsum sandstone, natural slate sandstone, artificial and natural stone, masonry, screed. These are high quality disc wheels, suitable for sanding marble, ceramic tile, concrete and rocks. High diamond concentration can improve durability and remove rough effectively. Our segmented grinders are suitable for die 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 fast grinding of concrete, masonry, stone and other masonry products. The wear-resistant metal bond is combined with diamond, and its grain size and concentration are specially designed to be suitable for grinding. It's an effective way to remove material and prolong life! The cutting wheels are specially designed for angle grinders, concrete grinders, concrete grinders , wall sander systems and floor sanders. The cutting discs use diamonds that are extremely resistant to shocks and high temperatures - they are perfectly combined with wear-resistant metal connections.< /p> Feature: Type: Diamond wheel Working materials: concrete, lightweight concrete, granite, artificial and natural stone, floor slab Diameter: 125 mm Hole: 22.2 mm Scope of delivery: 1 piece Note: The data is manual measurement, please allow 1-18cm error, due to the light and screen differences, there will be a certain color difference, the specific received in kind prevail.
