Diamax SCRG4 – 4″ Cyclone Diamond Cluster Grinding Wheel

The Diamax SCRG4 – 4″ Cyclone Diamond Cluster Grinding Wheel is a compact yet powerful surface preparation tool engineered for fast material removal and controlled grinding on hard surfaces. Designed for professional stone fabricators and concrete specialists, this wheel delivers aggressive cutting performance while maintaining a more uniform surface finish compared to traditional segmented grinding cups.

Constructed with strategically placed raised diamond cluster points, the SCRG4 concentrates grinding force across multiple contact areas to maximize efficiency. The flat-tip cluster design allows for aggressive stock removal while producing a smoother, more even surface profile. This makes it particularly effective for removing excess material, leveling high spots, and preparing slabs prior to polishing or honing.

Ideal for use on engineered stone, granite, quartz, concrete, and epoxy or adhesive residues, the SCRG4 performs exceptionally well in both fabrication shops and on job sites. It efficiently removes coatings, thinset, glue buildup, and surface imperfections without gouging or creating deep, uneven scratches that complicate later finishing stages.

The 4″ diameter provides excellent maneuverability and control, making it well-suited for detailed grinding, edge shaping, and working in tighter areas where larger grinding wheels may be less practical. Compatible with most standard 4″ angle grinders, it integrates easily into existing tool setups for seamless workflow.

Engineered for durability and consistent performance, the SCRG4’s diamond bond matrix is built to withstand demanding applications while maintaining cutting efficiency over time. The open cluster configuration also helps reduce loading and improve debris clearance, ensuring steady grinding action throughout the job.

Whether you are shaping edges, preparing slabs for polishing, or removing stubborn adhesives and coatings, the Diamax SCRG4 Cyclone Diamond Cluster Grinding Wheel offers the strength, precision, and reliability professionals depend on for high-quality surface preparation.
