Diamax SCRG5MB – 5″ Cyclone Steel-Back Diamond Cluster Grinding Wheel (Medium 50 Grit)
The Diamax SCRG5MB – 5″ Cyclone Steel-Back Diamond Cluster Grinding Wheel (Medium 50 Grit) is a heavy-duty surface preparation tool engineered for rapid, controlled grinding on hard natural and engineered materials. Designed for professional stone fabricators, installers, and concrete specialists, this grinding wheel delivers aggressive stock removal while maintaining stability and precision.
Built with a durable steel backing plate, the SCRG5MB offers exceptional rigidity and strength under high-pressure grinding applications. The solid steel body minimizes flex and vibration, allowing for consistent surface contact and improved operator control. This stable construction is especially important when working on dense materials such as engineered stone, granite, concrete, quartz, and similar hard surfaces.
The wheel features multiple diamond cluster segments strategically mounted across the grinding surface. These cluster points maximize cutting efficiency by increasing surface contact while maintaining strong material removal rates. The medium 50 grit configuration provides a balanced grinding profile—aggressive enough for effective leveling and surface preparation, yet controlled enough to leave a smoother finish compared to coarse grinding wheels.
Ideal for tasks such as flattening uneven slabs, removing high spots, eliminating surface imperfections, and preparing surfaces prior to polishing or coating applications, the SCRG5MB improves workflow efficiency in both fabrication shops and job-site environments.
The 5″ diameter is compatible with most standard variable-speed angle grinders, making it easy to integrate into professional grinding and surface preparation systems.
