Product Specification
7” x 5/8”-11 THREADED ARROW TYPE DIAMOND GRINDING CUP WHEEL
Built for aggressive surface grinding, leveling, and heavy stock removal, the Benchmark Abrasives 7” Arrow Type Diamond Grinding Cup Wheel is designed for concrete, granite, marble, masonry, and natural stone. Its arrow-style diamond segments create a concentrated grinding pattern for removing high spots, correcting uneven surfaces, and preparing hard mineral surfaces for coating, finishing, or additional surface work.
The larger 7” diameter provides greater grinding coverage for larger surface-preparation jobs, while the 7 mm diamond segments provide a tall diamond-bearing wear section. A direct-thread 5/8"-11 UNC hub mounts to compatible grinding equipment, making this wheel well suited for concrete preparation, construction, renovation, restoration, and stone work.

Machine Compatibility
For use with 7” angle grinders.
Compatible examples include:
-
Makita® GA7011C 7" Angle Grinder — 6,000 RPM; 5/8"-11 threaded mounting with a compatible 7" surface-grinding dust shroud. For dry grinding when permitted by the wheel marking.
Other models may also fit. Match the mounting, speed rating and required guard to your tool.
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.
