Siapower 1550 Siapan 6-Inch Sanding Discs: 400 Grit Ultra-Fine Polishing
Achieve a Glass-Like Finish with Premium 400 Grit Abrasives
The Siapower 1550 Siapan 6″ Sanding Disc in 400 grit is the professional choice for ultra-fine surface refinement and final-stage polishing. These discs are specifically engineered to handle delicate tasks such as sanding between coats of lacquer, scuffing clear coats, and prepping high-gloss surfaces. The high-performance aluminum oxide grain ensures an incredibly uniform scratch pattern, allowing you to achieve a flawless, swirl-free finish that is ready for buffing or final topcoat application.
Enhanced 15-Hole Vacuum System for Pristine Surface Results
Equipped with a precision 15-hole pattern, these discs provide superior dust extraction to maintain a perfectly clean work surface. At the 400-grit level, fine dust can quickly clog the abrasive, but the Siapower 1550 vacuum design ensures that particles are instantly removed. This airflow management prevents pilling and heat buildup, significantly extending the life of each disc in the 50-piece box while protecting sensitive coatings from friction damage during the final finishing stages.
