Diamax 4″ Cyclone 3.5mm Polishing Disk (30–3000 Grit)

The Diamax 4″ Cyclone 3.5mm Polishing Disk (30–3000 grit) is a professional multi-step polishing system designed to deliver complete surface finishing for natural and engineered stone, including granite, marble, quartz, and engineered stone. Engineered for progressive polishing, this disk allows operators to efficiently transition from heavy material removal and leveling to ultra-fine, high-gloss finishing, achieving a professional-quality surface in a single, continuous workflow.

With a 3.5mm thickness, this Cyclone Polishing Disk provides optimal rigidity and support while maintaining the flexibility needed to conform to edges, curves, and detailed profiles. Its wide grit range, from 30 (coarse) to 3000 (ultra-fine), enables stepwise surface refinement, eliminating saw marks, scratches, and minor surface imperfections, and preparing stone surfaces for high-gloss finishing without the need for multiple tools.

This disk is compatible with hand-held angle grinders, air polishers, and other polishing machines, making it versatile for both shop-based fabrication and on-site stone installation. Its resin-bond diamond construction ensures consistent cutting and polishing performance, long lifespan, and high abrasion resistance, even when used on dense, hard stone materials.

Designed for wet polishing applications, the 4″ Cyclone Disk reduces heat buildup, extends diamond life, and minimizes dust, while delivering even material removal and flawless surface finishes. It is particularly well-suited for edges, inside curves, corners, and intricate details where precise control and consistent results are critical.
