Siapower 1550 Siapan 6-Inch Sanding Discs: Precision 220 Grit Finishing

Refine Your Surfaces with Professional 220 Grit Performance

The Siapower 1550 Siapan 6″ Sanding Disc in 220 grit is the definitive choice for intermediate to fine surface smoothing. Perfectly balanced for the final sanding of raw wood or the preparation of primer surfacers, these discs remove minor imperfections while leaving a uniform, paint-ready texture. The high-quality aluminum oxide grain ensures a consistent scratch pattern, making it an essential tool for automotive refinishers and fine woodworkers who demand excellence in every layer of their work.

Optimized 15-Hole Configuration for Reliable Dust Extraction

Featuring a classic 15-hole pattern, these discs are engineered to provide efficient vacuum airflow across the most common orbital sander backing pads. This multi-hole design effectively channels fine 220-grit dust away from the abrasive surface, significantly reducing “pilling” and preventing the disc from loading prematurely. By keeping the interface cool and clean, the Siapower 1550 ensures a longer service life per disc, providing the reliability needed for high-volume production environments in this 50-disc box.
