Product Specification
4” x 5/8”-11 THREADED SWIRL TYPE DIAMOND GRINDING CUP WHEEL
Built for fast, controlled surface grinding and leveling, the Benchmark Abrasives 4” Swirl Type Diamond Grinding Cup Wheel is designed for concrete, granite, marble, masonry, and natural stone. Its swirl-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 construction, renovation, restoration, and stone-grinding applications.

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.
- 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.
