Diamax Cyclone ¾″ Small Diameter Resin Drum #400

The Diamax Cyclone ¾″ Small Diameter Resin Drum #400 is a high-performance resin-bond diamond polishing drum specifically engineered for fast, precise shaping and polishing of tight-radius and intricate areas on stone surfaces such as granite, marble, quartz, and engineered stone. Its compact ¾″ diameter makes it ideal for sink cutouts, inside corners, detailed profiles, and other hard-to-reach areas where larger polishing pads or wheels cannot provide consistent contact.

Featuring a coarse #400 grit, this resin drum is designed for aggressive material removal while maintaining controlled, clean grinding. It allows fabricators and stone professionals to efficiently remove high spots, shape edges, smooth rough surfaces, and refine tight radii, preparing the stone for subsequent finer polishing steps. The combination of diamond abrasives and resin bond ensures durable performance, consistent results, and extended tool life, even under demanding use.

Designed for wet polishing applications, the #400 drum uses water to cool the tool, reduce dust and slurry, and prolong the life of the resin bond. Wet use also improves grinding efficiency and helps achieve a smooth, even finish, minimizing chipping and surface damage.
