The Star Type 250mm Silver Brazed Grinding Disc is engineered for heavy-duty concrete surface preparation. Featuring a lightweight steel core and advanced silver brazing technology, this grinding plate delivers aggressive material removal, exceptional durability, and smooth grinding performance. Designed for use with floor grinders, it is ideal for stripping tough coatings (epoxies, urethanes), feathering uneven joints, smoothing rough concrete, and restoring floors to a pristine finish.
Available in 10-inch (250mm) diameter, this disc combines high-speed grinding with extended lifespan, making it a cost-effective solution for both professional contractors and industrial applications.
Features and Applications
✅ Star-Profiled Segments
Specially designed star-shaped segments enhance grinding aggressiveness and efficiency.
Ensures faster removal of hard coatings and uneven surfaces.
✅ Silver Brazed Technology
High-frequency silver brazing secures diamond segments firmly, preventing breakage during intense grinding.
✅ Light Steel Core
Reduces overall tool weight for easier handling and reduced operator fatigue.
Maintains structural stability for consistent performance.
✅ Multi-Grit Options
Choose from Coarse (35/40), Medium (50/60), or Fine (100/120) diamond grits to match surface finish requirements:
Coarse: Rapid material removal on heavily damaged surfaces.
Medium: Balanced grinding for general preparation.
Fine: Smooth finishing for polished results.
✅ Versatile Application
Compatible with dry and wet grinding setups.
Suitable for soft, hard, abrasive, or dusty concrete floors.
✅ Durable Bond System
Customizable bond hardness to match concrete conditions:
Hard Bond: Ideal for soft, abrasive concrete.
Medium Bond: For standard concrete surfaces.
Soft Bond: Optimized for hard, dense concrete.
Coating Removal: Efficiently strip epoxy, urethane, and other stubborn coatings.
Surface Leveling: Feather uneven joints, slab panels, or patched areas.
Concrete Smoothing: Refine rough surfaces or prepare floors for polishing.
Industrial Maintenance: Ideal for warehouses, garages, and commercial spaces.

Note
To choose the right diamond floor grinding shoe and diamond grinding cup wheels from suppliers, you must know the hardness of your concrete.
Concrete can be soft, hard, abrasive, dusty and brittle, etc. There are no two floors are ever the same, typically they are more abrasive when the floor is new or have a high sharp sand content. The more abrasive the floor the harder bond you will need to get the best performance out of the diamonds.
Bond - The strength of the metal binder that holds the diamond grit in the segment. Typically, the harder the bond the longer the life. Soft concrete needs the hard bond, medium-hard bond for medium concrete, and soft bond for hard concrete.
Choose Arrow segment, choose aggressiveness grinding plate!
