4″inch 100*16mm Diamond Polishing Disc 3 Steps 5 Steps Diamond Disc for Stone and Concrete
Product Overview
Engineered for precision stone restoration, this 3-Step Diamond Polishing Disc utilizes electroplated diamond clusters 40/60/120 mesh gradation with nickel-cobalt alloy bonding. The segmented rim design enhances cooling efficiency by 35% compared to conventional discs, achieving 0.02mm/s material removal rates on granite and marble. Its color-coded step system coarse/medium/fine allows sequential polishing from 60-3000 grit finishes, while the 2.5mm aluminum core maintains flatness tolerance within ±0.1mm during 15,000 RPM operation.
Product Advantages
1. Consistent Surface Finish: The innovative engineering of these discs ensures a uniform scratch-free texture, eliminating deep gouges while safeguarding underlying materials during polishing.
2. Even Pressure Distribution: Their adaptive pressure-balancing mechanism allows seamless sanding of complex geometries, including curves and angles, with no risk of uneven wear or surface deformation.
3. Dust-Free Sanding Experience: This disc enables clean, low-dust processing, ideal for wet sanding applications, it reduces airborne particulates and maintains a pristine work environment.
