1550 Siapower 6″ Sanding Disc 100 Grit – 81 Hole Pack

High-Speed Removal with Ceramic Technology

The 1550 Siapower 6″ sanding disc (100 Grit) is a powerhouse abrasive designed for heavy stock removal and rapid shaping. Featuring a high-performance mixed grit with ceramic content, this disc cuts faster and stays sharp longer than standard aluminum oxide abrasives. It is the perfect choice for the initial stages of sanding, effectively leveling body filler, stripping old coatings, and shaping hard materials like glass-fiber reinforced plastic (GRP) and wood with aggressive efficiency.

Superior Dust Extraction with 81-Hole Design

Engineered for the modern professional workshop, this version features an advanced 81-hole pattern. This multi-hole configuration significantly improves airflow and dust extraction compared to standard hole patterns. By clearing dust almost instantly from the surface, it prevents the abrasive from clogging (loading) and keeps the work area cleaner. Supported by a robust d-wt FSC-certified paper backing, the disc maintains stability and edge wear resistance even under heavy machine pressure.

Durable Performance for Tough Substrates

The 1550 Siapower 100 grit is built to handle the most demanding surfaces without losing its cutting power. The resin-over-resin bonding locks the ceramic-infused grains in place, ensuring a consistent scratch depth that makes subsequent refining steps easier. whether you are sanding out uneven edges on repaired surfaces, removing impurities from metal, or flatting composite materials, this disc delivers a uniform finish that professionals can rely on for high-quality surface preparation.
