Product Specification
7” X 5/8”-11 THREADED T-TYPE DIAMOND GRINDING CUP WHEEL
Built for aggressive surface grinding, leveling, and stock removal, the Benchmark Abrasives 7” T-Type Diamond Grinding Cup Wheel is designed for concrete, granite, marble, masonry, and natural stone. Its T-Type diamond segment layout is intended for productive material removal when correcting uneven surfaces, removing high spots, and preparing hard mineral surfaces for coating, finishing, or additional surface work.
The larger 7” diameter provides increased grinding coverage for slabs and broader 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, and the wheel is rated up to 8,700 RPM for demanding concrete preparation, 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.
- Wet or dry grinding is permitted only when the machine is also approved for the selected operating method.
- 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.
