Product Specification
4” X 5/8”-11 THREADED TURBO DIAMOND GRINDING CUP WHEEL
Built for fast, controlled surface grinding and stock removal, the Benchmark Abrasives 4” Turbo Diamond Grinding Cup Wheel is designed for concrete, granite, marble, masonry, and natural stone. Its turbo-style diamond segment layout is well suited for smoothing uneven surfaces, removing high spots, and preparing hard mineral materials for coating, finishing, or additional surface work.
The compact 4” diameter gives operators excellent control for localized grinding and edge work, 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 13,580 RPM for demanding concrete preparation, renovation, restoration, and stone-grinding applications.

Machine Compatibility
For use with 4” angle grinders.
Compatible examples include:
-
Milwaukee® 6117-33D Angle Grinder — 11,000 RPM maximum; 5/8"-11 threaded mounting with the manufacturer’s 4"/5" 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 13,580 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.
