Diamax Cyclone S RockBuster
Take your stone-fabrication performance and safety to the next level with the Diamax Cyclone S RockBuster. Engineered to outperform and completely replace traditional silicon-carbide grinding stones, the RockBuster delivers faster grinding, smoother control, cleaner work, and significantly higher operator safety.
NEW Critical Safety Advantage
Unlike silicon-carbide grinding stones, the Cyclone S RockBuster will NOT explode during use.
Its resin-bonded, rubber-backed construction eliminates the dangerous cracking and catastrophic wheel failures common with brittle silicon-carbide stones, making it a much safer, more reliable option for professional fabricators.
Use it with confidence on high-speed grinders and air polishers without the fear of shattering stones, flying debris, or hazardous breakage.
Why Professionals Are Switching to RockBuster
MUCH Safer Than Silicon-Carbide Wheels
Durable resin construction prevents breakage and eliminates the explosion risk associated with traditional silicon-carbide stones. This makes it ideal for shop and field use where operator safety is a priority.
10 mm Radius Edge for Precision Work
Designed with the same radius profile fabricators rely on, perfect for sink corners, tight radius areas, and detailed shaping.
Dust-Reduced Grinding for Cleaner Work Areas
Dramatically lowers airborne dust compared to silicon-carbide wheels, improving air quality and cutting cleanup time.
Fast, Aggressive Stock Removal
The 30 and 50 grits chew through material quickly, outperforming SiC wheels in both speed and consistency.
Smooth Final Blending & Finish Prep
The 100 and 200 grits deliver clean, controlled finishing on seams, miters, edges, and ultra-compact surfaces.
Rubber-Backed for Low Vibration
Less vibration means better control, smoother grinding, and reduced operator fatigue.
Use Wet or Dry – Total Jobsite Flexibility
Suitable for concrete, granite, engineered stone, marble, and ultra-compact materials.
