Siapower 1550 Siapan 6-Inch Sanding Discs: 600 Grit Super-Fine Finishing

Achieve Professional Grade Polish with Ultra-Fine 600 Grit

The Siapower 1550 Siapan 6″ Sanding Disc in 600 grit is precision-engineered for the final refinement stages of your project. This super-fine abrasive is perfect for removing minor surface imperfections, leveling clear coats, and sanding between paint layers for a flawless, glass-like finish. Whether you are working on high-end automotive detailing, lacquer finishing, or solid surface polishing, these discs provide a soft touch with high-efficiency results, ensuring your final topcoat is smooth and ready for buffing.

Advanced 81-Hole Technology for Dust-Free Surface Perfection

Equipped with a high-density 81-hole multi-hole pattern, these discs offer the most advanced dust extraction available. At the 600-grit level, even the smallest dust particles can cause surface marring or “pigtails” if not removed instantly; the Siapower 1550 vacuum system eliminates this risk by keeping the work surface perfectly clean. This superior airflow prevents the fine grit from clogging and reduces heat buildup, significantly extending the life of each disc in the 50-pack for maximum workshop economy.
