Siapower 1550 Siapan 6-Inch Sanding Discs: Ultra-Fine 320 Grit Finishing

Achieve a Superior Final Finish with 320 Grit Precision

The Siapower 1550 Siapan 6″ Sanding Disc in 320 grit is meticulously crafted for the high-end finishing stages of any professional project. This ultra-fine abrasive is perfect for scuffing primers, sanding between topcoats, and smoothing delicate surfaces before the final paint or lacquer application. Utilizing premium aluminum oxide grains, these discs provide an incredibly consistent scratch pattern that ensures maximum coating adhesion and a flawless, swirl-free surface that meets the highest industrial standards.

Advanced 15-Hole Pattern for Clean and Cool Finishing

Designed for precision work, the integrated 15-hole vacuum system provides essential dust management to prevent surface marring. At the 320-grit level, fine dust particles can easily accumulate and cause “pilling” or heat buildup; however, the Siapower 1550 design ensures continuous airflow to keep the disc sharp and the workpiece clean. This efficient extraction technology extends the lifespan of the 50-disc box, allowing professionals to maintain a high-quality output with fewer disc changes and a healthier workspace.
