Product Specification
7” x 5/8”-11 THREADED DOUBLE ROW DIAMOND GRINDING CUP WHEEL
Built for broad-area surface grinding, leveling, and stock removal, the Benchmark Abrasives 7” Double Row Diamond Grinding Cup Wheel is designed for concrete, granite, marble, masonry, and natural stone. Its larger diameter provides greater grinding coverage for floors, slabs, and other expansive surfaces where efficient material removal and surface correction are the priority.
The double row segment layout provides consistent contact with the work surface, while the 5 mm diamond segments support general-purpose grinding and leveling. A direct-thread 5/8"-11 UNC hub mounts to compatible grinding equipment, and the wheel is rated up to 8,700 RPM for demanding construction, renovation, restoration, and stone-grinding applications.

Safety Tips
- Never exceed the wheel’s maximum rated speed of 8,700 RPM.
- Inspect the diamond segments, steel body, and threaded hub before each use.
- Do not use a cracked, damaged, bent, or excessively worn cup wheel.
- Confirm the grinder uses the correct 5/8"-11 threaded spindle.
- Thread the cup wheel fully and securely onto the spindle according to the machine manufacturer’s instructions.
- Use a guard or dust shroud designed for diamond cup-wheel grinding.
- Maintain controlled contact with the work surface and avoid excessive pressure.
- Do not use this cup wheel as a cut-off blade.
- Use only the grinding method marked on the wheel and approved for the machine. Never add water to a dry-use grinder.
- Use appropriate eye, hearing, respiratory, hand, and other required personal protective equipment.
- Grinding concrete, masonry, granite, marble, and other silica-containing materials can generate respirable silica dust. Use appropriate water-delivery or dust-extraction controls.
