Siapower 1550 Siapan 6-Inch Sanding Discs: 400 Grit Ultra-Fine Finishing

Achieve a Mirror-Like Finish with Premium 400 Grit Abrasives

The Siapower 1550 Siapan 6″ Sanding Disc in 400 grit is designed for the most delicate sanding tasks where a perfect, swirl-free surface is non-negotiable. Ideal for fine-surface leveling, sanding between coats of lacquer, and polishing clear coats, these discs provide an incredibly smooth touch. The high-quality aluminum oxide grain is distributed evenly to ensure that your final finish is uniform, making it the preferred choice for automotive professionals and high-end furniture makers.

Maximum Efficiency with Advanced 81-Hole Dust Extraction

Equipped with a sophisticated 81-hole multi-hole pattern, these discs offer the ultimate solution for a clean and healthy workspace. At the 400-grit level, dust particles are extremely fine and can quickly clog standard sandpaper; however, the Siapower 1550 vacuum technology ensures that debris is instantly removed. This prevents pilling and heat buildup, significantly extending the life of each disc in the 50-piece box while maintaining a cool cutting temperature for sensitive surfaces.
